Everett Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Everett 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 Everett's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the May 28–June 18 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends September 21. Wherever the today marker sits, the nearest color change is your next appointment.
The Everett pool calendar
Opening — target June 4
Target June 4; the practical window runs May 28–June 18, and the 7-day mean crosses the 61°F threshold around June 18. Cold-water starts are the cheap ones.
Closing — deadline September 21
The window opens September 11 once water leaves the algae zone; the model deadline is September 21, a week ahead of the November 2 freeze normal.
Estimated water temperature by month
This is Everett'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 41° | 42° | 44° | 48° | 54° | 59° | 63° | 66° | 63° | 56° | 48° | 42° |
The curve peaks near 66°F — comfortable-water months here usually involve a heater or a solar cover.
