Winter Haven Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Winter Haven 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.
Each dot is one week of Winter Haven'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 62°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 233-day prime stretch, lighter but never zero through winter.

Spring refresh
No forced dates: the 7-day mean never leaves the swim-viable range (floor 62.1°F). Spring refresh and winter care replace opening and closing.

Estimated water temperature by month
This is Winter Haven's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 63° | 64° | 67° | 71° | 77° | 81° | 83° | 84° | 83° | 80° | 73° | 67° |
Warmest water typically June–October (peaking near 84°F); heaters and covers shift any month up.
