Bonita Springs Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
Bonita Springs runs a twelve-month pool calendar — the model finds no week cold enough to force a closing. This page tracks the water-temperature curve and the prime-season stretch; the spring refresh and winter care guides cover the routines that replace opening and closing here. Keep it bookmarked as the between-guides dashboard for the year.
Bonita Springs, FL — 252 swim days a yearEach dot is one week of Bonita Springs's year, and here they're all solid teal — the model finds no off-season to draw. What varies instead is comfort: the water table below shows the seasonal range from 64°F to 84°F, and the today marker tells you where in that cycle you're standing. Maintenance follows the same curve — heavier through the 252-day prime stretch, lighter but never zero through winter.

Estimated water temperature by month
Monthly averages of the site's water model run on Bonita Springs's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 65° | 66° | 68° | 72° | 76° | 80° | 82° | 83° | 83° | 80° | 74° | 69° |
Warmest water typically June–October (peaking near 84°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Boca Raton's pool season and Boynton Beach's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Florida season index.
