Reno Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Reno'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 Reno's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the May 2–May 23 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 12. Wherever the today marker sits, the nearest color change is your next appointment.
The Reno pool calendar
Opening — target May 9
Open by May 9 — a two-week head start on the May 23 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 12
Hold the cover until October 2, then winterize by October 12, a week ahead of the October 27 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Reno'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 36° | 38° | 43° | 48° | 55° | 64° | 74° | 77° | 72° | 61° | 49° | 38° |
The curve peaks near 78°F — comfortable-water months here usually involve a heater or a solar cover.
