Mableton Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Mableton'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.
The bar compresses Mableton's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 30–April 20 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 25. Wherever the today marker sits, the nearest color change is your next appointment.
The Mableton pool calendar
Opening — target April 6
Open by April 6 — a two-week head start on the April 20 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 25
The window opens October 15 once water leaves the algae zone; the model deadline is October 25, a week ahead of the November 7 freeze normal.
Estimated water temperature by month
This is Mableton's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 43° | 44° | 50° | 57° | 64° | 71° | 76° | 76° | 74° | 66° | 56° | 48° |
The curve peaks near 76°F — comfortable-water months here usually involve a heater or a solar cover.
