Anaheim Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Anaheim's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Anaheim's swim season; the hollow teal run before it (February 8 to March 1) is when to open; the hollow amber run after is when to close, with December 10 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Anaheim pool calendar
Opening — target February 15
Open by February 15 — a two-week head start on the March 1 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline December 10
Hold the cover until November 30, then winterize by December 10, a week ahead of the December 25 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Anaheim'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 60° | 60° | 61° | 64° | 67° | 70° | 74° | 77° | 77° | 74° | 68° | 61° |
The curve peaks near 78°F — comfortable-water months here usually involve a heater or a solar cover.
