Galveston Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Galveston'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.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Galveston's swim season; the hollow teal run before it (February 3 to February 24) is when to open; the hollow amber run after is when to close, with December 12 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Galveston pool calendar
Opening — target February 10
Target February 10; the practical window runs February 3–February 24, and the 7-day mean crosses the 61°F threshold around February 24. Cold-water starts are the cheap ones.
Closing — deadline December 12
Hold the cover until December 2, then winterize by December 12, a week ahead of the January 7 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Galveston'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 57° | 57° | 62° | 69° | 75° | 82° | 85° | 86° | 84° | 79° | 70° | 62° |
Warmest water typically June–October (peaking near 86°F); heaters and covers shift any month up.
