Kent Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Kent'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 Kent's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the May 14–June 4 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 1. Wherever the today marker sits, the nearest color change is your next appointment.
The Kent pool calendar
Opening — target May 21
Open by May 21 — a two-week head start on the June 4 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 1
Hold the cover until September 21, then winterize by October 1, a week ahead of the November 10 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Kent'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° | 43° | 46° | 50° | 56° | 61° | 66° | 69° | 65° | 58° | 49° | 43° |
The curve peaks near 69°F — comfortable-water months here usually involve a heater or a solar cover.
