Redmond Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Redmond's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
The bar compresses Redmond's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the May 24–June 14 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 Redmond pool calendar
Opening — target May 31
Open by May 31 — a two-week head start on the June 14 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 23 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Redmond'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 42° | 43° | 45° | 49° | 54° | 60° | 64° | 68° | 65° | 58° | 50° | 44° |
The curve peaks near 68°F — comfortable-water months here usually involve a heater or a solar cover.
