“Tropical and Humid”

Sanibel Island is definitively tropical and humid. The high humidity can catch some people off guard, but it is not something that is unknown to the rest of Florida.

Floridians and consistent visitors to the state will be accustomed to the high humidity and “heavy” heat of Florida, especially during the summer.

But, Sanibel Island fares much better overall. Because the island is right on the water, and surrounded by it, you get a captivating gulf breeze that offsets the humidity. The breeze cools the region down tremendously.

Anyone who has spent considerable time in the center of the state or its coasts will be very familiar with the staggering difference in how the air “feels.”

Though it may not be much cooler strictly temperature-wise on Sanibel Island, the ocean breeze is an absolute breath of fresh, brisk, and welcoming air. It truly makes a massive difference.

Of course, Sanibel Island, and the whole of Florida isn’t extremely hot year-round. Sanibel, in fact, has a predictable range of pleasant temperatures throughout the year that makes it more than just a perfect seasonal vacation home.

Seasonal Temperatures

The coolest temperatures of Sanibel Island are from January to April, however because it’s so much warmer than the rest of the country, it’s a peak time to visit. It reaches into the mid 70s degrees every day, with dips to the mid-50s in the evening and night.

The fall often remains a steady 75 to 80 degrees, though peaks in the upper-80s are common during fall or spring. But the nice breeze keeps things at a nice equilibrium.

While it can be even hotter during the summer, well into the 90s on many days, plentiful ocean activities and cooler temperatures in the evening and early morning help to offset the heat.


Rainfall is common, but it is rarely unwelcomed. The rainfall cools off the streets and offsets the heat. Like many tropical regions, June is the peak of rainy season. Throughout May to July, rainfall occurs frequently. Showers are short (often only 15 minutes) and most often occur in the late afternoons.

Despite this, rain is actually rather uncommon during the cooler months of January to April. Overall, Sanibel Island impresses with about 262 sunny days every year. The United States average is around 200, so this accounts for at least two entire extra months of radiant sunshine. With temperatures virtually never dipping below 50 degrees, it hardly gets better.

Places of Pure Quiet Beauty

There are plenty of places to really absorb the fullness of the beautiful year-long weather. Just over half of the entire island is made up of wildlife refuges. These protected and somewhat isolated areas offer the ideal escape into the Florida island tropics.

The largest reserve is the famous Ding Darling National Wildlife Refuge. Its 5,200 epic acres feature staggering and thick mangroves, pines, and wildly different seasons of wildlife. You can find the famous pink Florida flamingos standing tall in the shallow waters.

Every season is ideal for birding, while the late summer and fall is a wonderful time to see sea turtles, alligators, and various species of fish like snook and redfish.

The fact that Sanibel Island is a beautiful tropical paradise makes the pleasant weather that much better. Consider making Sanibel Island your home. We can help guide you through the available Sanibel Island real estate.
