Mauldin Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Mauldin'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 Mauldin's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 31–April 21 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 22. Wherever the today marker sits, the nearest color change is your next appointment.
The Mauldin pool calendar
Opening — target April 7
Open by April 7 — a two-week head start on the April 21 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 22
The window opens October 12 once water leaves the algae zone; the model deadline is October 22, a week ahead of the November 7 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Mauldin'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 41° | 42° | 48° | 56° | 64° | 71° | 77° | 77° | 74° | 65° | 54° | 46° |
The curve peaks near 78°F — comfortable-water months here usually involve a heater or a solar cover.
