Bright, beautiful, and colorful all day long, the beaches on Sanibel Island are the place to be for travelers who love that classic Florida sunshine. While Florida has some amazing attractions and dazzling open beaches, it’s the weather that really keeps people coming back time and time again. In fact, you can’t enjoy the attractions and the beaches if the weather is poor.
Thankfully, Sanibel Island weather is truly spectacular. We take a look at what you can expect throughout the year.
The Cool Air
Sanibel Island has a very distinct advantage compared to many other tourist-heavy locales in Florida. Sanibel Island sits directly on the gulf. As a matter of fact, if you look at Sanibel Island on a map, you see that it is surrounded by wide water on both sides. Compared to nearby cities like Cape Coral and Sarasota, Sanibel Island is extended out into the gulf, with miles of water between any side of the island and more land.
Its narrow profile also allows the cool gulf breeze to sweep over it. Sanibel Island is just three miles wide. You can actually bike or walk from one side of Sanibel to the other in a single afternoon.
No matter where you are on the island, you are bound to enjoy those sweeping gulf winds.
According to the facts about Sanibel, The cool season typically runs from early December to early March. This is often peak tourism season, as visitors flock to the island to escape their snow-drenched homes in the northeast. The average temperature is about 75 degrees during the cool season.
Despite gulf breezes and months of welcoming brisk air during the peak of winter, Sanibel Island can get a little toasty. The breeze helps cool things off, but you can still expect the hot season to run from late May into early October. The temperature hovers an average of 86 degrees, with the peak of the heat settling in right in the first two weeks of August.
