Last updated: July 25, 2026 · dates · water temp
Macon'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.
Macon, GA — 172 swim days a yearThe bar compresses Macon's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 11–April 1 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 3. Wherever the today marker sits, the nearest color change is your next appointment.
The Macon pool calendar
Opening — target March 18
Target March 18; the practical window runs March 11–April 1, and the 7-day mean crosses the 61°F threshold around April 1. Cold-water starts are the cheap ones.
Closing — deadline November 3
The window opens October 29 once water leaves the algae zone; the model deadline is November 3, a week ahead of the November 10 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Macon'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 48° | 49° | 55° | 61° | 69° | 77° | 82° | 82° | 79° | 71° | 60° | 52° |
Warmest water typically July–September (peaking near 83°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Mableton's pool season and Roswell's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Georgia season index.
