Palmdale Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Palmdale 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.
Palmdale, CA — 166 swim days a yearThe bar compresses Palmdale's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 29–April 19 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 6. Wherever the today marker sits, the nearest color change is your next appointment.
The Palmdale pool calendar
Opening — target April 5
Target April 5; the practical window runs March 29–April 19, and the 7-day mean crosses the 61°F threshold around April 19. Cold-water starts are the cheap ones.
Closing — deadline November 6
Hold the cover until October 27, then winterize by November 6, a week ahead of the November 19 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Palmdale'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 46° | 48° | 53° | 58° | 64° | 72° | 80° | 83° | 80° | 71° | 59° | 49° |
Warmest water typically July–September (peaking near 83°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Oxnard's pool season and Palo Alto's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the California season index.
Palmdale pool season FAQ
When should I open my pool in Palmdale, CA?
Target April 5. That date backs off two weeks from the day Palmdale's 7-day mean temperature reaches 61°F, so you start up in cold, algae-resistant water. Work the full checklist in the Palmdale opening guide.
When should I close my pool in Palmdale?
The closing deadline is November 6 — late enough that the water has cooled out of the algae zone, early enough to beat Palmdale's first-freeze normal by about a week. See the Palmdale closing guide for the winterizing steps.

Palmdale averages 166 days a year with normal highs of 80°F or better — about 4 days later than the California median. The California season index ranks all 147 covered cities by the same metric.
