Austin Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Austin'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 Austin's swim season; the hollow teal run before it (February 16 to March 9) is when to open; the hollow amber run after is when to close, with November 24 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Austin 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 24
Hold the cover until November 14, then winterize by November 24, a week ahead of the December 3 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Austin'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° | 81° | 85° | 87° | 84° | 76° | 66° | 57° |
Warmest water typically June–September (peaking near 87°F); heaters and covers shift any month up.
