Orem Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Orem's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
Orem, UT — 108 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Orem's swim season; the hollow teal run before it (April 25 to May 16) is when to open; the hollow amber run after is when to close, with October 7 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Orem pool calendar
Opening — target May 2
Target May 2; the practical window runs April 25–May 16, and the 7-day mean crosses the 61°F threshold around May 16. Cold-water starts are the cheap ones.
Closing — deadline October 7
The window opens September 27 once water leaves the algae zone; the model deadline is October 7, a week ahead of the October 19 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Orem'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 29° | 31° | 40° | 48° | 57° | 67° | 76° | 78° | 71° | 59° | 46° | 34° |
Warmest water typically August–August (peaking near 79°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Ogden's pool season and Provo's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Utah season index.
Orem pool season FAQ
When should I open my pool in Orem, UT?
Target May 2. That date backs off two weeks from the day Orem's 7-day mean temperature reaches 61°F, so you start up in cold, algae-resistant water. Work the full checklist in the Orem opening guide.
When should I close my pool in Orem?
The closing deadline is October 7 — late enough that the water has cooled out of the algae zone, early enough to beat Orem's first-freeze normal by about a week. See the Orem closing guide for the winterizing steps.
How long is the swim season in Orem?
Orem averages 108 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.
How warm does pool water get in Orem?
An unheated pool near Orem typically peaks around 79°F in high summer and bottoms out near 28°F in winter, never quite reaching the 78°F comfort line without a heater or solar cover. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
