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 Utah 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 Utah
The fairest way to compare Utah 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.
Utah pool climate at a glance
High elevation means intense summer sun but chilly nights and late-spring snow along the Wasatch Front, while low-desert St. George in the south swims far longer. In model terms that makes Utah a short-season state. The spread shows up clearly on the local pages: compare St. George's pool season with Ogden's and the difference is measured in weeks, not days. Neighbors in the index run on their own normals too — see Texas and Vermont for the adjacent calendars.
Utah pool season FAQ
When do pools open in Utah?
Model openings in Utah run from April 5 in St. George to May 24 in Logan, with the statewide median on May 2. 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 Utah?
The median Utah closing deadline is October 10, 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 Utah city has the longest swim season?
St. George leads with 164 days of 80°F+ highs per year, while Logan brings up the rear at 83 days. The chart above ranks every covered city by the same metric.
