Huntington Beach Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Huntington Beach 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.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Huntington Beach's swim season; the hollow teal run before it (March 10 to March 31) is when to open; the hollow amber run after is when to close, with December 2 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Huntington Beach pool calendar
Opening — target March 17
Open by March 17 — a two-week head start on the March 31 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline December 2
Hold the cover until November 22, then winterize by December 2, a week ahead of the December 25 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Huntington Beach'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° | 58° | 59° | 61° | 64° | 67° | 71° | 73° | 74° | 70° | 65° | 59° |
The curve peaks near 74°F — comfortable-water months here usually involve a heater or a solar cover.
