Indio Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Indio 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.
Indio, CA — 241 swim days a yearThe bar compresses Indio's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the January 18–February 8 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends December 6. Wherever the today marker sits, the nearest color change is your next appointment.
The Indio pool calendar
Opening — target January 25
Target January 25; the practical window runs January 18–February 8, and the 7-day mean crosses the 61°F threshold around February 8. Cold-water starts are the cheap ones.
Closing — deadline December 6
The window opens November 26 once water leaves the algae zone; the model deadline is December 6, a week ahead of the December 27 freeze normal.
Estimated water temperature by month
This is Indio's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 57° | 60° | 66° | 72° | 78° | 86° | 92° | 94° | 92° | 84° | 72° | 60° |
Warmest water typically May–October (peaking near 95°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Huntington Beach's pool season and Inglewood's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the California season index.
Indio pool season FAQ
When should I open my pool in Indio, CA?

The closing deadline is December 6 — late enough that the water has cooled out of the algae zone, early enough to beat Indio's first-freeze normal by about a week. See the Indio closing guide for the winterizing steps.
