The Horizon West 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 31
Hold the cover until December 27, then winterize by December 31, a week ahead of the January 9 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Horizon West'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 61° | 61° | 65° | 69° | 75° | 80° | 82° | 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 Homestead's pool season and Jacksonville's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Florida season index.
