Lexington Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Lexington'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 Lexington's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 9–April 30 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 17. Wherever the today marker sits, the nearest color change is your next appointment.
The Lexington pool calendar
Opening — target April 16
Target April 16; the practical window runs April 9–April 30, and the 7-day mean crosses the 61°F threshold around April 30. Cold-water starts are the cheap ones.
Closing — deadline October 17
Hold the cover until October 7, then winterize by October 17, a week ahead of the October 28 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Lexington'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 35° | 35° | 42° | 52° | 62° | 70° | 76° | 76° | 73° | 63° | 51° | 41° |
The curve peaks near 77°F — comfortable-water months here usually involve a heater or a solar cover.
