What the columns mean
"Open by" is the recommended spring date — two weeks before the city's 7-day mean temperature crosses 61°F, the model's proxy for water approaching the 65°F algae-growth zone. "Close by" is the fall deadline — ten days after the water leaves that zone, capped a week ahead of the local 50% first-freeze date. "80°F+ days" counts days whose normal high reaches 80°F: the length of the true warm-swim season, and the fairest single number for comparing Rhode Island cities against each other.
Every figure comes from each city's own NOAA 1991–2020 normals station (named in its guide's footer), so neighboring cities can legitimately differ by a few days. The season overview linked from each row adds the live water-temperature model and the full-year season bar; the state hubs above carry the step-by-step checklists.

Rhode Island pool climate at a glance
Ocean State springs warm slowly because of cool Atlantic waters, so pools open later than the latitude suggests, but maritime warmth lingers pleasantly into September. In model terms that makes Rhode Island a moderate-season state. The spread shows up clearly on the local pages: compare Pawtucket's pool season with Providence's and the difference is measured in weeks, not days. Neighbors in the index run on their own normals too — see Pennsylvania and South Carolina for the adjacent calendars.
