Last updated: July 25, 2026 · dates · water temp
Brooklyn Park'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.
Brooklyn Park, MN — 67 swim days a yearThe bar compresses Brooklyn Park's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the May 3–May 24 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends September 29. Wherever the today marker sits, the nearest color change is your next appointment.
The Brooklyn Park pool calendar
Opening — target May 10
Open by May 10 — a two-week head start on the May 24 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline September 29
The window opens September 19 once water leaves the algae zone; the model deadline is September 29, a week ahead of the October 8 freeze normal.
Estimated water temperature by month
This is Brooklyn Park'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 17° | 17° | 27° | 40° | 53° | 64° | 72° | 72° | 67° | 55° | 41° | 27° |
The curve peaks near 73°F — comfortable-water months here usually involve a heater or a solar cover.
Every station tells its own story: compare this curve with Bloomington's pool season and Duluth's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Minnesota season index.
