Redding Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Redding'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.
The bar compresses Redding's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 2–April 23 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 4. Wherever the today marker sits, the nearest color change is your next appointment.
The Redding pool calendar
Opening — target April 9
Open by April 9 — a two-week head start on the April 23 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 4
Hold the cover until October 25, then winterize by November 4, a week ahead of the November 21 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Redding'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 47° | 49° | 53° | 57° | 64° | 73° | 81° | 83° | 78° | 70° | 58° | 49° |
Warmest water typically July–September (peaking near 84°F); heaters and covers shift any month up.
