Conroe Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Conroe'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.
The bar compresses Conroe's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 16–March 9 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 25. Wherever the today marker sits, the nearest color change is your next appointment.
The Conroe pool calendar
Opening — target February 23
Target February 23; the practical window runs February 16–March 9, and the 7-day mean crosses the 61°F threshold around March 9. Cold-water starts are the cheap ones.
Closing — deadline November 25
Hold the cover until November 15, then winterize by November 25, a week ahead of the December 2 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Conroe'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 52° | 54° | 60° | 67° | 73° | 80° | 84° | 85° | 83° | 76° | 66° | 57° |
Warmest water typically June–September (peaking near 86°F); heaters and covers shift any month up.
