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 Georgia 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.
Swim-season length across Georgia
The fairest way to compare Georgia 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.
Georgia pool climate at a glance
Long, humid summers open Georgia pools by mid-spring and keep them swimmable into fall, though the cooler north Georgia mountains trail the Atlanta area and coastal plain. In model terms that makes Georgia a long-season state. The spread shows up clearly on the local pages: compare Albany's pool season with Atlanta's and the difference is measured in weeks, not days. Neighbors in the index run on their own normals too — see Florida and Hawaii for the adjacent calendars.
Georgia pool season FAQ
When do pools open in Georgia?
Model openings in Georgia run from March 1 in Brunswick to April 6 in Mableton, with the statewide median on March 28. Each date is two weeks before that city's 7-day mean temperature crosses 61°F — early enough to start up in algae-cold water.
When should you close a pool in Georgia?
The median Georgia closing deadline is November 2, and every city's own deadline is capped a week ahead of its NOAA 50% first-freeze date. Closing late and cold beats closing early and warm — cool water holds its winter chemistry far better.
Which Georgia city has the longest swim season?
Albany leads with 184 days of 80°F+ highs per year, while Mableton brings up the rear at 104 days. The chart above ranks every covered city by the same metric.
