Toledo Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Toledo 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 Toledo's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 25–May 16 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 8. Wherever the today marker sits, the nearest color change is your next appointment.
The Toledo pool calendar
Opening — target May 2
Open by May 2 — a two-week head start on the May 16 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 8
The window opens September 28 once water leaves the algae zone; the model deadline is October 8, a week ahead of the October 27 freeze normal.
Estimated water temperature by month
This is Toledo'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 29° | 27° | 34° | 44° | 56° | 67° | 74° | 74° | 70° | 60° | 48° | 36° |
The curve peaks near 75°F — comfortable-water months here usually involve a heater or a solar cover.
