Davis Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Davis 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.
The bar compresses Davis'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 5. Wherever the today marker sits, the nearest color change is your next appointment.
The Davis pool calendar
Opening — target April 9
Target April 9; the practical window runs April 2–April 23, and the 7-day mean crosses the 61°F threshold around April 23. Cold-water starts are the cheap ones.
Closing — deadline November 5
Hold the cover until October 26, then winterize by November 5, a week ahead of the December 1 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Davis'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° | 49° | 53° | 57° | 63° | 70° | 74° | 75° | 74° | 69° | 59° | 50° |
The curve peaks near 75°F — comfortable-water months here usually involve a heater or a solar cover.
