Ogden Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Ogden'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.
Ogden, UT — 103 swim days a yearThe bar compresses Ogden's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 27–May 18 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 9. Wherever the today marker sits, the nearest color change is your next appointment.
The Ogden pool calendar
Opening — target May 4
Open by May 4 — a two-week head start on the May 18 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 9
The window opens September 29 once water leaves the algae zone; the model deadline is October 9, a week ahead of the October 23 freeze normal.
Estimated water temperature by month
This is Ogden's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 30° | 31° | 40° | 48° | 55° | 66° | 75° | 79° | 72° | 60° | 47° | 35° |
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 Logan's pool season and Orem's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Utah season index.
Ogden pool season FAQ
When should I open my pool in Ogden, UT?
The site model recommends opening by May 4 — about two weeks before Ogden'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 Ogden opening guide.
When should I close my pool in Ogden?
Winterize by October 9. The model holds the deadline a week ahead of Ogden's NOAA 50% first-freeze date, so the plumbing is protected before the first hard night. The full sequence is in the Ogden closing guide.
How long is the swim season in Ogden?
Ogden averages 103 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 Ogden?
