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 New York 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.

The fairest way to compare New York cities is the number of days with 80°F+ normal highs — the practical warm-swim season. Every bar links to that city's one-page season overview with the live water model.
New York pool climate at a glance
Downstate humidity gives New York City a dependable Memorial Day to Labor Day season, while upstate, the Adirondacks, and lake-effect zones run markedly shorter and cooler. In model terms that makes New York a moderate-season state. The spread shows up clearly on the local pages: compare Staten Island's pool season with Saratoga Springs's and the difference is measured in weeks, not days. Neighbors in the index run on their own normals too — see New Mexico and North Carolina for the adjacent calendars.
