Kissimmee Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Kissimmee's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
Each dot on the bar is one week of Kissimmee's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (January 12–February 2), solid teal is swim season, and hollow amber is the closing window ending December 30. The black marker is today — its position against the colors is the entire executive summary.
The Kissimmee pool calendar
Opening — target January 19
Target January 19; the practical window runs January 12–February 2, and the 7-day mean crosses the 61°F threshold around February 2. Cold-water starts are the cheap ones.
Closing — deadline December 30
Hold the cover until December 25, then winterize by December 30, a week ahead of the January 6 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Kissimmee'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 61° | 61° | 64° | 69° | 74° | 79° | 82° | 83° | 82° | 79° | 71° | 65° |
Warmest water typically June–October (peaking near 83°F); heaters and covers shift any month up.
