Camarillo Pool Season: the Year on One Bar
Last updated: July 25, 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.
Camarillo, CA — 23 swim days a yearEach 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.
Every station tells its own story: compare this curve with Burbank's pool season and Carlsbad's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the California season index.
Camarillo pool season FAQ
When should I open my pool in Camarillo, CA?
Open by April 15 — the model places Camarillo's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Camarillo opening guide has the 12-step sequence.
When should I close my pool in Camarillo?
Close by November 24: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Camarillo closing guide sequences the work backward from that date.
How long is the swim season in Camarillo?
Camarillo averages 23 days a year with normal highs of 80°F or better — about 14 days later than the California median. The California season index ranks all 147 covered cities by the same metric.
How warm does pool water get in Camarillo?
An unheated pool near Camarillo typically peaks around 70°F in high summer and bottoms out near 56°F in winter, never quite reaching the 78°F comfort line without a heater or solar cover. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
