The South Fulton pool calendar
Opening — target March 25
Open by March 25 — a two-week head start on the April 8 crossing keeps startup chemistry small and beats the local service rush.

The window opens October 25 once water leaves the algae zone; the model deadline is November 4, a week ahead of the November 20 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on South Fulton'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 45° | 46° | 52° | 60° | 68° | 75° | 80° | 81° | 78° | 70° | 59° | 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 Savannah's pool season and Valdosta's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Georgia season index.
