Norman Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Norman'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 Norman's swim season; the hollow teal run before it (March 31 to April 21) is when to open; the hollow amber run after is when to close, with October 27 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Norman pool calendar
Opening — target April 7
Open by April 7 — a two-week head start on the April 21 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 27
The window opens October 18 once water leaves the algae zone; the model deadline is October 27, a week ahead of the November 3 freeze normal.
Estimated water temperature by month
This is Norman'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 39° | 40° | 47° | 56° | 64° | 74° | 80° | 82° | 78° | 67° | 56° | 45° |
Warmest water typically July–September (peaking near 82°F); heaters and covers shift any month up.
