Sanibel Island Vacation Rentals
February 10, 2020

If you’ve decided that you’re going to vacation on Sanibel Island, but don’t know the best time to visit, we’re here to help you. From sun, sea, and sand to sports, extreme activities, and stunning nature, you don't want to miss out on this incredible experience. Of course, it's not as straightforward as booking flights and accommodation because there is a lot of research required. The last thing anybody wants to do is turn up in the off-season when Sanibel Island doesn't meet your expectations.

The best time to visit Sanibel Island will ultimately depend on what you’re looking for. If you want to visit during the peak season, this typically occurs between December and April. During this time, the weather is warmer than most of the U.S. with few days of rain and no threat of hurricanes. Even during the off-season though, Sanibel Island has plenty to offer, making it nearly impossible to choose a bad time to visit. 

Since everyone has a different idea of their dream vacation, it’s helpful to know what Sanibel Island is like throughout the year. The comprehensive guide below provides you with a complete picture of the island so that you can decide when you want to visit.

Where is Sanibel Island?

Before you can visit and understand Sanibel Island, you first need to know its location. While some of you will probably have an idea already, others might not, yet still include Sanibel Island on your bucket list. Great! The more people that see how incredible this hot spot is, the better, in our opinion. Like many highly sought after vacation places in the US, Sanibel Island is located in Florida. However, it's on the west coast of the 'Sunshine State' in the tropical waters of the Gulf of Mexico.

The closest major city is Fort Myers, with the beach a stone's throw away. On clear days, you can see the island of Sanibel from mainland Florida. Still, you don't have to be in nearby Fort Myers to access Sanibel. As long as you're on the west coast of Florida, whether it's the Everglades or further north in Tampa, you're only a short journey from this stunning vacation spot. Even Miami and Fort Lauderdale on the east side of Florida are less than three hours away.

This makes Sanibel Island very accessible regardless of the time of year. All you need to do is hop in the car and you can be there in a couple of hours. Don't worry if you're not a Florida native because Sarasota and Fort Myers airports are very close and offer fantastic commuting options.

What is Sanibel Island Known For?

While Sanibel Island is known and loved by people for many different reasons, most will argue it’s most well-known as a shelling destination. The barrier islands off the west coast of Florida are known for their 'shell life' due to their position in the Gulf of Mexico. Sanibel, however, runs differently - east to west instead of south to north - allowing it to catch multiple currents. Plus, there isn't a shelf. As a result, tons of shells wash up on the beach in the thousands, with travelers and locals alike doing the 'Sanibel stoop,' the bent over posture that people are in when they’re looking for shells on the beach.

If the idea of sifting through shells on the beach isn’t your idea of a dream vacation, it’s ok.  Sanibel Island has plenty more to offer its guests regardless of the time of year. Probably the most iconic activity is to visit the J.N. "Ding" Darling National Wildlife Refuge. The refuge is a conservationist center that helps protect the mangroves on Sanibel, as well as the animals that call the groves home. Don't be shocked if you spot crocodiles or alligators basking on the bank while you hike along Wildlife Drive and look down on the water. Cuckoos and Ospreys stop off for a rest as they migrate from South to North.

Aside from hiking with the inhabitants of the island and searching for shells, Sanibel is known for its beaches. One of the favorites is Bowman's Beach because it's open from 7 am to 7 pm daily, and has all the amenities families and individuals need. As well as picnic tables and grills that allow you to cook and prepare food around the year, there are bike racks. 

The Climate of Sanibel Island

Sanibel Island is in Florida on the Gulf of Mexico, which means it's hot all-year-round, right? While this is true relative to the majority of the U.S., the climate in Sanibel still changes along with the seasons. Therefore, it’s important to know what the weather is like throughout the year so that you choose the best time to go based on the weather you prefer.

Fall and Winter Weather on Sanibel Island

Fall and winter months run from October to March. During this period, you can expect:

  • Average temperatures to hit lows of 73°F
  • January to be the coldest month
  • November, December, and February temperatures not to reach above 80°F
  • Temperatures to be as low as 54°F

Of course, a high of 73°F in the coldest season of the year is still very pleasant. There's no doubt that 54°F is chilly, particularly for this part of the country, but most places in America are lucky if they get temps of 34°F in January. Relatively, Sanibel is an excellent place for a winter staycation as the climate is cool and pleasant without being overbearing or freezing cold.

Spring and Summer on Sanibel Island

Here's what you'll experience weather-wise on Sanibel during the spring and summer months:

  • Average highs of above 90°F in June, July, and August
  • Peak highs of 91°F in July and August
  • Lows of 60°F in the spring
  • Almost 9 inches of rainfall during June, the most for the whole year

Although the climate is at its hottest during the spring and summertime, Sanibel does get a lot of rain. This shouldn't discourage visitors from checking out the island during the summer though. There are still plenty of things to do on Sanibel Island when it rains.  That's why visitors prefer to opt for the spring rather than summer as the best time to visit Sanibel Island. April is the driest month, with just over an inch of rain, and the average low temp is only 63°F. Highs hit 84°F, only 7°F lower than in July and August, so it's not as if spring is cold. 

Remember that you should choose the best time to visit Sanibel based on your likes and dislikes. Some people love the sun, whereas others like the weather to be pleasant without being sticky. The fantastic thing about the climate on Sanibel is that there is a season for everyone's specifications.

What is there to do on Sanibel Island?What is There to do on Sanibel Island

Your trip should be packed with fun activities, and that's why it's important to learn more about the things you can do on Sanibel. Sometimes, the idea of an idyllic island isn't enough. To stop the novelty from wearing off, you need to fill your time with exciting, enjoyable activities. We've already spoken about the wildlife aspect of Sanibel, and we'll go into the shelling element of the island later on. For now, let's tackle a selection of the stuff you don't know about that appeals to a wide range of people.

On Sanibel Island, you can:

  • Go snorkeling or scuba diving. Sanibel is famous for its wrecks and man-made reefs. Yes, they aren't natural, but they are practical as they help to replenish fish stocks. As well as fishermen, divers and snorkels get to enjoy an eclectic mix of underwater critters.
  • Go fishing. Chartered boats head out into the gulf regularly, offering everyone from newbies to experienced fishers the chance to catch various types of fish. Florida is famed for its Marlin, but there are also Snapper, Mackerel, and varieties of shark.
  • Hop on a cruise. Not only does a cruise provide you with a chance to island-hop, but Sanibel cruises are also eco-friendly to lower pollution and preserve the wildlife of Sanibel. That means you have a better chance of running into a pod of dolphins.
  • Check out Sanibel's history. Whether it's the Bailey-Matthews National Shell Museum or Edison and Ford Winter Estates, there's a lot to learn about this obscure island.
  • Hit the gym. Let's face it - vacations can get a little indulgent. If you feel as if you need to hit the treadmill, there are multiple spas and health clubs at your disposal. A yoga class is perfect if you fancy improving your core without doing anything too strenuous. Island Cinema is an alternative if you prefer to take the edge off with a movie, popcorn and soda.

The seasons can impact the activities offered, so you should plan ahead. For instance, boat tours and cruises can't leave the bay in bad or inclement weather. Thankfully, there are plenty of bars, restaurants, and day trips to keep you occupied whatever the weather on the island is!

Peak Season on Sanibel Island

Unlike the majority of vacation or holiday home destinations, the peak season on Sanibel runs from December through to April. Therefore, the island is an excellent option for holiday-goers or anybody who needs a break in the winter and spring months. From the beginning of December up until mid-April, you can expect the island to be at its liveliest.

Compared to other popular tourist locations in Florida, Sanibel doesn’t get extremely crowded, even during the busy season. However, if you’re still concerned about vacationing during peak season, you can choose to come during the off-season. Booking a vacation during the off-season in Sanibel can lead to some lower rates than what you’ll find during the other parts of the year. Thankfully, this also comes without sacrificing much of what makes Sanibel so great.

Year-round Fun in Sanibel Island

Okay then, what about year-round fun in Sanibel? If you're going to avoid the peak season, the island must be fun and accessible regardless of the time of year. Thankfully, the enjoyment never ends. 

Yes, cruises and fishing trips will depend on the weather because inclement conditions can prevent boats from venturing out of the bay. However, the museums stay open all year, although the opening and closing times may vary. Another year-around attraction is the Botanical Gardens at Sanibel Moorings Resort. Legend has it that a rogue gardener took it upon himself to plant exotic varieties of plants and flowers, with other gardeners adding to his collection. Now, the different greenery on show is vast, so much so that it was declared an official botanical garden in 2009. Sanibel Moorings Resort runs tours for most of the year, which is perfect if you want to gaze at the vivid colors and textures of rare plants.

Should museums and gardens not be your thing, you can always rely on food. If you're not a foodie, you will be after your visit to Sanibel Island. Inspired by the Latin American and Caribbean cuisines that surround Florida, many of the local eateries use fresh seafood as the focal point of their menus. Whether it's rice and snapper with jerk spices or fish tacos, it's hard to beat a day sampling the dishes on and off the beaten track. Lazy Flamingo lets you bring your own ingredients and the chefs there will cook it for you, so all you need to do is make sure you catch your dinner on your fishing tour!

Sanibel Island in Winter

Sanibel Island in winter is very popular, and there is an eclectic mix of tourists. Why? It's mainly because of the climate. In the winter, it's:

  • Around 75°F, so the weather is delightful.
  • Not raining. The rainy season doesn't start until the summer, which means the days and nights are dry without being overbearingly warm.

Some of these reasons make Sanibel Island an incredible getaway for Americans who no longer want to brave the cold conditions back home. Some vacationers that visit Sanibel Island in the winter fall in love and end up purchasing a home and becoming snowbirds

Sanibel Island in SpringSanibel Island in Spring

As tourist destinations go, spring on Sanibel Island is pretty special. If you go at the start of the season, you'll catch the throng of vacationers and bird-watchers that have left the U.S. for warm weather recuperation. The atmosphere on the island is electric thanks to the droves of people in bars and restaurants, and on the beach. Once it hits mid-spring, the crowds level out, and you're left with a unique piece of the island to yourself, something most visitors don't get to experience. It's for this reason, and the fact that the weather is perfect, that May is viewed as one of the best times to visit Sanibel Island. The last throes of spring still provide a fantastic buzz, while many vacationers have left and the rain won't make an appearance for another couple of weeks.

Summer on Sanibel Island

Summer is the off-season. If you're wondering why it's due to the rain and threat of hurricanes. From June through September, you can expect an average of 7 inches to fall throughout the four months. Temperatures can also get pretty high, with the average high hitting more than 90°F, making the weather a bit too hot for some peoples’ tastes. If you don't like being this warm, then summertime might not be the top choice for you. Of course, there are benefits of visiting the Sanibel and Captiva islands from July to August. They include:

  • Lower prices. Lower demand means hotels, restaurants, and tours will sometimes lower their prices.
  • Breaks in the weather. The heat can be intense, but the rain showers that can occur daily are brilliant at providing tourists a break from the warm conditions.
  • Lower tides. The tides are at their lowest in the spring; however, they start to recede at the end of the summer. Therefore, the quality of shelling can be excellent.
  • Less congestion. Since fewer visitors are on the island during the summer months, there’s more space for you to enjoy it. 

Summertime on Sanibel Island is a fantastic opportunity if you're willing to put up with the high temperatures. Lots of people enjoy tropical climates, so summer could be perfect, especially if you like low prices and less vacation congestion. 

Fall on Sanibel Island

Fall on Sanibel Island is also known as 'shoulder season.' In layman's terms, it's the period between summer and autumn when there is a bit of a lull in tourism. For many people, it's the best time of the year to visit Sanibel because it mirrors the conditions in May. The climate is warm without being sticky, and the peak season is still a few months away, meaning that the prices don't skyrocket. Another factor to keep in mind is that the school year is back in session, and there are fewer families and children.

What makes September to November enticing, however, is the shelling. Tides are low during the fall, leaving a range of shells on the beach for you to pick. It's like taking candy from a baby for shelling enthusiasts! And, you don't need a guide since the beaches are accessible. Merely make your way to Bowman's, or any nearby beach, and walk down the sand until you hit a patch with shells on full display. A word of warning: please be careful. Tides can be unpredictable, and you should make your way back to shore if the water is too intense.

The Best Time to Visit Sanibel Island: Knowing When to Book

With all this information on the climate and the best activities, it can be a little daunting. There are so many reasons to go to Sanibel that it's tough to choose the perfect season. An excellent tip is to try and understand the features that will make or break your trip. For instance, it's not wise to visit in the summer if you hate humidity. On the other hand, the high prices might rule out going in summer and spring if your budget is relatively modest.

With that in mind, here is a selection of things you can do to ensure your vacation is fun and affordable regardless of the season:

  • Book in advance. As obvious as it sounds, hotels, and car rental rates in peak season are cheaper if you buy them months in advance. You might have to check prices as early as the summer for the following winter if you want to go in December.
  • Be on the lookout for last minute deals. This might seem counterproductive given that we just recommended booking in advance. However, great properties can also be found this way. Last minute cancellations and unoccupied properties aren’t completely unheard of. These lead to properties being available for lower than normal rates. Many companies will have a special deals section or newsletter that travelers can sign up for.
  • Drive part of the way. One thing that will increase the cost of your holiday in peak or off-season is flying. Flights can be affordable, but they are rarely cheap. Therefore, driving to Fort Myers will save you money that you can spend on other areas of your trip.
  • Travel on public holidays. This tip might sound surprising because public holidays tend to be expensive. However, the day of the holiday isn't as most people are already at their destination. As a result, flying is usually quite cheap as long as you don't mind missing part of the action for a day.
  • Use your credit card. Specific cards often reward you with perks for using it for everyday purchases. So, buying the groceries can build up air miles or car rental points, both of which you can use to make your vacation more affordable. The trick is to switch to a card company that focuses on travel. Many companies will also offer special promotions where additional points and miles can be earned or redeemed, so be on the lookout. 

Once you know the best conditions for you and your family, it's not as difficult to reduce the cost of your vacation as you might imagine. The hacks above work all year-round - you only need to get organized to bag a bargain on Sanibel Island. You'll also find that property types can vary greatly in terms of their offering. For example, there are more Sanibel Island condo rentals available than other property types which in many cases leads to a cheaper rental price. This is unlike Sanibel Island villa rentals, which are few and far between making them more exclusive and sought after.

When is Hurricane Season on Sanibel Island?When is Hurricane Season on Sanibel Island

Technically, hurricane season in the Gulf of Florida is from the start of June to the end of October. However, it's important to understand that this encompasses the entire Atlantic coast of America, which includes Sanibel. Of course, because Sanibel is on Florida's west coastline, it's sheltered from the worst of the action until the second half of the season. This means September is often billed as the peak time for hurricanes and storms on Sanibel Island.

Don't worry if you plan on visiting Sanibel during the shoulder season and now you're scared. Yes, hurricanes are possible during this period, but you shouldn't let the idea of a storm get in the way of your trip. These stats should make things clearer:

  • Between 1960 and 2017, 12 major hurricanes hit the Floridian mainland (major is classed as cat 3 and above).
  • Of the 12, only 4 have been within the Sanibel region.
  • 'Close' means 50 miles or less.
  • That means there have been 4 big hurricanes near Sanibel Island in almost 60 years.

As you can see, the shoulder season after the summer isn't a massive gamble. After all, the area averages a category 3 hurricane once every 15 years, which isn't bad. And, the last big one to hit Florida's Southwest coast was Irma in 2017, and that was much further south.

What is the Best Month for Shelling on Sanibel Island?

There's no doubt that the answer to this question is September to November. This period is when the tides are low enough for you to venture out onto beaches that are usually deep in water. Of course, accessibility isn't the only thing that makes the standard of shelling so high in the fall. Autumn also means:

  • The sun sets earlier. Mollusks are nocturnal and come out at night. Fewer daylight hours in the fall mean there are more shells to spot.
  • Beaches are open. Bad weather in the summer can force beaches to close. Thankfully, the fall climate is less dramatic, and the likes of Blind Pass, Turner Beach, and Lighthouse Beach should be accessible.
  • Regulations are tighter. Shelling is fun, yet the welfare of the animals should be everyone's main concern. Otherwise, they won't be around for much longer!

November is the month that stands out the most. It's when hurricane season comes to an end, but also when the turtle nesting period is over too. As a result, you can use artificial lights again and shell into the late hours.

With that being said, there isn't a bad time or month for shelling on Sanibel Island. Shells wash onto the shores every single day making, shelling on Sanibel Island a year-round favorite.

Things to Do on Sanibel Island

If shelling and chilling on the beach isn't enough, along with the rest of the activities you'll find on Sanibel, you'll be happy to hear that there is more. Hopping on a ferry to nearby Captiva is a must as it's as beautiful as Sanibel itself. And don't forget that longer excursions are possible. From Sanibel, you can visit:

  • Cayo Costa
  • Boca Grande
  • Pine Island
  • Key West
  • Everglades National Park
  • Tampa 
  • Miami

There are also lots of activities for kids. Parents that bring their children will be glad to know that dolphin and manatee spotting, paddleboarding, and cycling are all possible. Looking for something more grown-up while the kids frolic at sea school? Sanibel's farmers' market is run by locals and sells fresh, organic produce every Sunday. 

No matter what you decide to spend your time doing, it's nearly impossible to run out of things to do on Sanibel Island.
