South Fulton Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of South Fulton'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.
The bar compresses South Fulton's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 18–April 8 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 4. Wherever the today marker sits, the nearest color change is your next appointment.
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.
Closing — deadline November 4
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.
