Orem Pool Season: the Year on One Bar
Last updated: July 15, 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.
Reading 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.
