Spring Hill Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Spring Hill pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
Spring Hill, FL — 230 swim days a yearThe bar compresses Spring Hill's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the January 14–February 4 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends December 25. Wherever the today marker sits, the nearest color change is your next appointment.
The Spring Hill pool calendar
Opening — target January 21
Target January 21; the practical window runs January 14–February 4, and the 7-day mean crosses the 61°F threshold around February 4. Cold-water starts are the cheap ones.
Closing — deadline December 25
Hold the cover until December 24, then winterize by December 25, a week ahead of the January 1 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Spring Hill'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 60° | 61° | 65° | 69° | 75° | 80° | 83° | 83° | 82° | 79° | 71° | 65° |
Warmest water typically June–October (peaking near 83°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Sebring's pool season and St. Augustine's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Florida season index.
