Clovis Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Clovis'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 Clovis's swim season; the hollow teal run before it (March 21 to April 11) is when to open; the hollow amber run after is when to close, with November 9 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Clovis pool calendar
Opening — target March 28
Target March 28; the practical window runs March 21–April 11, and the 7-day mean crosses the 61°F threshold around April 11. Cold-water starts are the cheap ones.
Closing — deadline November 9
Hold the cover until October 30, then winterize by November 9, a week ahead of the December 14 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Clovis'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 47° | 50° | 55° | 60° | 67° | 74° | 82° | 83° | 80° | 72° | 60° | 50° |
Warmest water typically July–September (peaking near 84°F); heaters and covers shift any month up.
