Santa Maria Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Santa Maria 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 Santa Maria's swim season; the hollow teal run before it (May 22 to June 12) is when to open; the hollow amber run after is when to close, with November 5 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Santa Maria pool calendar
Opening — target May 29
Target May 29; the practical window runs May 22–June 12, and the 7-day mean crosses the 61°F threshold around June 12. 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 13 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Santa Maria'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 52° | 53° | 54° | 56° | 58° | 60° | 63° | 64° | 64° | 63° | 60° | 54° |
The curve peaks near 64°F — comfortable-water months here usually involve a heater or a solar cover.
