Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Apple Valley 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.
Apple Valley, CA — 156 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Apple Valley's swim season; the hollow teal run before it (April 6 to April 27) is when to open; the hollow amber run after is when to close, with November 1 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Apple Valley pool calendar
Opening — target April 13
Open by April 13 — a two-week head start on the April 27 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 1
The window opens October 22 once water leaves the algae zone; the model deadline is November 1, a week ahead of the November 11 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Apple Valley'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 45° | 47° | 51° | 56° | 63° | 71° | 79° | 81° | 78° | 69° | 57° | 47° |
Warmest water typically July–September (peaking near 81°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Antioch's pool season and Arden-Arcade's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the California season index.
