Provo Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Provo pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
Provo, UT — 119 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Provo's swim season; the hollow teal run before it (April 24 to May 15) is when to open; the hollow amber run after is when to close, with October 10 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Provo pool calendar
Opening — target May 1
Open by May 1 — a two-week head start on the May 15 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 10
Hold the cover until September 30, then winterize by October 10, a week ahead of the October 21 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Provo's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 32° | 34° | 43° | 50° | 57° | 67° | 76° | 79° | 73° | 61° | 48° | 37° |
Warmest water typically August–August (peaking near 80°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Orem's pool season and Salt Lake City's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Utah season index.
Provo pool season FAQ
When should I open my pool in Provo, UT?
The site model recommends opening by May 1 — about two weeks before Provo's 7-day mean temperature crosses 61°F, while the water is still too cold for algae. The step-by-step sequence is in the Provo opening guide.
When should I close my pool in Provo?
Winterize by October 10. The model holds the deadline a week ahead of Provo's NOAA 50% first-freeze date, so the plumbing is protected before the first hard night. The full sequence is in the Provo closing guide.

Provo averages 119 days a year with normal highs of 80°F or better — right on the statewide median. The Utah season index ranks all 12 covered cities by the same metric.
