Tuscaloosa Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Tuscaloosa pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
Each dot on the bar is one week of Tuscaloosa's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (March 13–April 3), solid teal is swim season, and hollow amber is the closing window ending November 3. The black marker is today — its position against the colors is the entire executive summary.
The Tuscaloosa pool calendar
Opening — target March 20
Open by March 20 — a two-week head start on the April 3 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 3
The window opens October 25 once water leaves the algae zone; the model deadline is November 3, a week ahead of the November 10 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Tuscaloosa'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 46° | 47° | 53° | 61° | 68° | 76° | 81° | 82° | 79° | 71° | 59° | 51° |
Warmest water typically July–September (peaking near 82°F); heaters and covers shift any month up.
