What is the Weather Like in Sanibel Island, Florida?

Sanibel Island is the ultimate vacation destination if you’re looking for a Florida getaway. You’ll be able to experience all the fun in the sun you expect from the Sunshine State, but you’ll avoid the huge crowds you find in cities like Orlando and Tampa. Come take advantage of the gorgeous wildlife, white sand beaches, mouth-watering seafood, and so much more.

The weather in Sanibel Island is great all year round, but there are certain changes throughout the individual seasons. No matter what time of year you plan to visit, our Sanibel Island condo rentals provide the perfect place to rest your head at night. Here is a breakdown of the annual Sanibel Island weather.


While winter is cooler in Sanibel Island, it is certainly not as cold as you may experience in other parts of the United States. During the winter months of December, January, and February, the average high temperatures range in the mid-70s, while low temperatures stay around 50 degrees. This is the perfect weather to experience outdoor activities with just a light jacket in the evening hours.

You won’t have to bring an umbrella on vacation with you during the winter, as it is the middle of the dry season. Average rainfall in the winter months is less than 2 inches, so there should be no reason for the weather to alter your plans.

As the flowers begin to bloom, you’ll experience slightly higher temperatures in the spring. For the months of March, April, and May, the high temperatures range in the 80s, while lows stay in the high 50s and 60s. Consider bringing a light jacket for the evening, but enjoy the water during the morning and afternoon!

Rainfall in the spring is slightly higher as we move into the rainy season. March and April are relatively dry, but May starts to bring higher averages of rainfall. You may experience an afternoon shower that brings in the cool weather for the evening.


As you can probably expect, summer is the hottest season that Sanibel Island experiences. Average high temperatures for the months of June, July, and August range in the 90s, and low temperatures still stay warm in the 70s. This season is perfect for experiencing the indoor attractions, like the many Sanibel Island the museums and historical sites that provide a much-needed respite from the summer sun.

Summer is also the wet season for Sanibel Island, with average rainfall hovering around 8 or 9 inches for the summer months. This rain often comes in the form of an afternoon shower that cools everything down for relaxing and seashell hunting in the later hours. Consider bringing a raincoat or umbrella with you for your stay.

Finally, Sanibel Island sees a break from the heat in the fall months. Expect high temperatures for September, October, and November to range in the 80s, and low temperatures will remain in the 60s and 70s. Much like spring, you may consider bringing a sweater or jacket for nighttime.

The beginning of fall is still in the rainy season, so average rainfall in September hovers around 8 inches. However, as we move into the later fall months, rainfall totals average only 2 or 3 inches per month. You likely won’t need an umbrella on your trip, but you might consider an indoor activity if you run into an afternoon shower.
