Thousand Oaks Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Thousand Oaks's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
The bar compresses Thousand Oaks's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 8–April 29 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 24. Wherever the today marker sits, the nearest color change is your next appointment.
The Thousand Oaks 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
The window opens November 14 once water leaves the algae zone; the model deadline is November 24, a week ahead of the December 28 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Thousand Oaks'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 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.
