Providence Pool Season: the Year on One Bar
Last updated: July 25, 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.
Providence, RI — 69 swim days a yearEach 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.
Every station tells its own story: compare this curve with Pawtucket's pool season and Warwick's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Rhode Island season index.
Providence pool season FAQ
When should I open my pool in Providence, RI?
Open by May 10 — the model places Providence's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Providence opening guide has the 12-step sequence.
When should I close my pool in Providence?
Close by October 8: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Providence closing guide sequences the work backward from that date.
How long is the swim season in Providence?
Providence averages 69 days a year with normal highs of 80°F or better — right on the statewide median. The Rhode Island season index ranks all 4 covered cities by the same metric.
How warm does pool water get in Providence?
An unheated pool near Providence typically peaks around 75°F in high summer and bottoms out near 30°F in winter, never quite reaching the 78°F comfort line without a heater or solar cover. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
