Sandy Springs Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Sandy Springs'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.
Each dot on the bar is one week of Sandy Springs'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 26–April 16), solid teal is swim season, and hollow amber is the closing window ending October 27. The black marker is today — its position against the colors is the entire executive summary.
The Sandy Springs pool calendar
Opening — target April 2
Target April 2; the practical window runs March 26–April 16, and the 7-day mean crosses the 61°F threshold around April 16. Cold-water starts are the cheap ones.
Closing — deadline October 27
The window opens October 17 once water leaves the algae zone; the model deadline is October 27, a week ahead of the November 9 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Sandy Springs'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 43° | 44° | 50° | 58° | 66° | 74° | 78° | 80° | 76° | 68° | 56° | 48° |
Warmest water typically July–August (peaking near 80°F); heaters and covers shift any month up.
