Ogden Pool Season: the Year on One Bar
Last updated: July 15, 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.
The 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.
