Pasadena Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Pasadena pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
The bar compresses Pasadena's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 5–February 26 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends December 3. Wherever the today marker sits, the nearest color change is your next appointment.
The Pasadena pool calendar
Opening — target February 12
Target February 12; the practical window runs February 5–February 26, and the 7-day mean crosses the 61°F threshold around February 26. Cold-water starts are the cheap ones.
Closing — deadline December 3
Hold the cover until November 23, then winterize by December 3, a week ahead of the December 28 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Pasadena'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 55° | 57° | 62° | 68° | 74° | 81° | 84° | 85° | 83° | 77° | 68° | 60° |
Warmest water typically June–September (peaking near 85°F); heaters and covers shift any month up.
