Providence Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Providence'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 Providence's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (May 3–May 24), solid teal is swim season, and hollow amber is the closing window ending October 8. The black marker is today — its position against the colors is the entire executive summary.
The Providence pool calendar
Opening — target May 10
Target May 10; the practical window runs May 3–May 24, and the 7-day mean crosses the 61°F threshold around May 24. Cold-water starts are the cheap ones.
Closing — deadline October 8
The window opens September 28 once water leaves the algae zone; the model deadline is October 8, a week ahead of the October 30 freeze normal.
Estimated water temperature by month
This is Providence'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 32° | 30° | 36° | 45° | 55° | 64° | 72° | 74° | 70° | 60° | 49° | 40° |
The curve peaks near 75°F — comfortable-water months here usually involve a heater or a solar cover.
