Turlock Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Turlock'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.
The bar compresses Turlock's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 21–April 11 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 9. Wherever the today marker sits, the nearest color change is your next appointment.
The Turlock pool calendar
Opening — target March 28
Open by March 28 — a two-week head start on the April 11 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 9
The window opens October 30 once water leaves the algae zone; the model deadline is November 9, a week ahead of the December 20 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Turlock'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 48° | 51° | 56° | 60° | 66° | 72° | 78° | 79° | 77° | 71° | 60° | 51° |
Warmest water typically July–August (peaking near 80°F); heaters and covers shift any month up.
