Anniston Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
Anniston's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
Anniston, AL — 147 swim days a yearThe bar compresses Anniston's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 20–April 10 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 2. Wherever the today marker sits, the nearest color change is your next appointment.
The Anniston pool calendar
Opening — target March 27
Open by March 27 — a two-week head start on the April 10 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 2
Hold the cover until October 23, then winterize by November 2, a week ahead of the November 9 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Anniston'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 45° | 46° | 52° | 59° | 67° | 75° | 79° | 80° | 78° | 69° | 58° | 50° |
Warmest water typically July–September (peaking near 81°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Tuscaloosa's pool season and Auburn's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Alabama season index.
