Last updated: July 25, 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.
Sandy Springs, GA — 135 swim days a yearEach 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.

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.
Every station tells its own story: compare this curve with Roswell's pool season and Savannah's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Georgia season index.
