Torrance Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Torrance'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 Torrance's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 10–May 1 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 25. Wherever the today marker sits, the nearest color change is your next appointment.
The Torrance pool calendar
Opening — target April 17
Target April 17; the practical window runs April 10–May 1, and the 7-day mean crosses the 61°F threshold around May 1. Cold-water starts are the cheap ones.
Closing — deadline November 25
The window opens November 15 once water leaves the algae zone; the model deadline is November 25, a week ahead of the January 5 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Torrance'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 57° | 57° | 57° | 59° | 61° | 64° | 67° | 70° | 70° | 67° | 63° | 58° |
The curve peaks near 70°F — comfortable-water months here usually involve a heater or a solar cover.
