Charlottesville Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Charlottesville'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.
Each dot on the bar is one week of Charlottesville's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (April 7–April 28), solid teal is swim season, and hollow amber is the closing window ending October 19. The black marker is today — its position against the colors is the entire executive summary.
The Charlottesville pool calendar
Opening — target April 14
Open by April 14 — a two-week head start on the April 28 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 19
The window opens October 9 once water leaves the algae zone; the model deadline is October 19, a week ahead of the November 10 freeze normal.
Estimated water temperature by month
This is Charlottesville'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 37° | 37° | 43° | 52° | 62° | 70° | 77° | 77° | 73° | 64° | 53° | 44° |
The curve peaks near 78°F — comfortable-water months here usually involve a heater or a solar cover.
