Camarillo Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Camarillo'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.
Each dot on the bar is one week of Camarillo's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (April 8–April 29), solid teal is swim season, and hollow amber is the closing window ending November 24. The black marker is today — its position against the colors is the entire executive summary.
The Camarillo pool calendar
Opening — target April 15
Target April 15; the practical window runs April 8–April 29, and the 7-day mean crosses the 61°F threshold around April 29. Cold-water starts are the cheap ones.
Closing — deadline November 24
Hold the cover until November 14, then winterize by November 24, a week ahead of the December 28 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Camarillo'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 56° | 57° | 57° | 59° | 61° | 64° | 68° | 70° | 70° | 67° | 63° | 58° |
The curve peaks near 70°F — comfortable-water months here usually involve a heater or a solar cover.
