Medford Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Medford pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
The bar compresses Medford's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 27–May 18 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 14. Wherever the today marker sits, the nearest color change is your next appointment.
The Medford pool calendar
Opening — target May 4
Open by May 4 — a two-week head start on the May 18 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 14
Hold the cover until October 4, then winterize by October 14, a week ahead of the October 29 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Medford'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 39° | 42° | 46° | 50° | 57° | 64° | 72° | 76° | 71° | 62° | 50° | 42° |
The curve peaks near 76°F — comfortable-water months here usually involve a heater or a solar cover.
