Tuscaloosa Pool Season: the Year on One Bar
Last updated: July 25, 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.
Tuscaloosa, AL — 160 swim days a yearEach 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.
Every station tells its own story: compare this curve with Montgomery's pool season and Anniston's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Alabama season index.
Tuscaloosa pool season FAQ
When should I open my pool in Tuscaloosa, AL?

When should I close my pool in Tuscaloosa?
Winterize by November 3. The model holds the deadline a week ahead of Tuscaloosa's NOAA 50% first-freeze date, so the plumbing is protected before the first hard night. The full sequence is in the Tuscaloosa closing guide.

Tuscaloosa averages 160 days a year with normal highs of 80°F or better — right on the statewide median. The Alabama season index ranks all 10 covered cities by the same metric.
