Carmichael Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Carmichael 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 Carmichael's swim season; the hollow teal run before it (March 25 to April 15) 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 Carmichael pool calendar
Opening — target April 1
Open by April 1 — a two-week head start on the April 15 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 9
Hold the cover until October 30, then winterize by November 9, a week ahead of the December 16 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Carmichael'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 48° | 51° | 56° | 59° | 65° | 71° | 77° | 78° | 76° | 70° | 60° | 51° |
Warmest water typically August–August (peaking near 78°F); heaters and covers shift any month up.
