Montgomery Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Montgomery'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.
Montgomery, AL — 181 swim days a yearThe bar compresses Montgomery's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 24–March 17 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 11. Wherever the today marker sits, the nearest color change is your next appointment.
The Montgomery pool calendar
Opening — target March 3
Target March 3; the practical window runs February 24–March 17, and the 7-day mean crosses the 61°F threshold around March 17. Cold-water starts are the cheap ones.
Closing — deadline November 11
Hold the cover until November 4, then winterize by November 11, a week ahead of the November 18 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Montgomery'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 50° | 52° | 58° | 65° | 72° | 79° | 83° | 85° | 82° | 74° | 62° | 54° |
Warmest water typically June–September (peaking near 85°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Mobile's pool season and Tuscaloosa's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Alabama season index.
