El Paso de Robles Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
El Paso de Robles'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 El Paso de Robles's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 16–May 7 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 29. Wherever the today marker sits, the nearest color change is your next appointment.
The El Paso de Robles pool calendar
Opening — target April 23
Target April 23; the practical window runs April 16–May 7, and the 7-day mean crosses the 61°F threshold around May 7. Cold-water starts are the cheap ones.
Closing — deadline October 29
Hold the cover until October 19, then winterize by October 29, a week ahead of the November 10 freeze normal. Late and cold beats early and warm.

The curve peaks near 72°F — comfortable-water months here usually involve a heater or a solar cover.
