Vancouver Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Vancouver 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 Vancouver's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the May 12–June 2 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 5. Wherever the today marker sits, the nearest color change is your next appointment.
The Vancouver pool calendar
Opening — target May 19
Target May 19; the practical window runs May 12–June 2, and the 7-day mean crosses the 61°F threshold around June 2. Cold-water starts are the cheap ones.
Closing — deadline October 5
The window opens September 25 once water leaves the algae zone; the model deadline is October 5, a week ahead of the November 9 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Vancouver'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 40° | 42° | 45° | 50° | 55° | 61° | 67° | 70° | 67° | 59° | 50° | 43° |
The curve peaks near 70°F — comfortable-water months here usually involve a heater or a solar cover.
