Richmond Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Richmond pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
The bar compresses Richmond'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 November 8. Wherever the today marker sits, the nearest color change is your next appointment.
The Richmond 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 November 8
Hold the cover until October 29, then winterize by November 8, a week ahead of the January 2 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Richmond'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 51° | 52° | 55° | 57° | 59° | 62° | 63° | 63° | 65° | 65° | 60° | 53° |
The curve peaks near 65°F — comfortable-water months here usually involve a heater or a solar cover.
