College Station Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
College Station'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 College Station's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (February 19–March 12), solid teal is swim season, and hollow amber is the closing window ending November 23. The black marker is today — its position against the colors is the entire executive summary.
The College Station pool calendar
Opening — target February 26
Open by February 26 — a two-week head start on the March 12 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 23
Hold the cover until November 13, then winterize by November 23, a week ahead of the November 30 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on College Station'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° | 53° | 59° | 66° | 73° | 80° | 84° | 86° | 84° | 76° | 65° | 56° |
Warmest water typically June–September (peaking near 86°F); heaters and covers shift any month up.
