Youngstown Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Youngstown 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.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Youngstown's swim season; the hollow teal run before it (May 2 to May 23) is when to open; the hollow amber run after is when to close, with October 2 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Youngstown pool calendar
Opening — target May 9
Open by May 9 — a two-week head start on the May 23 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 2
Hold the cover until September 22, then winterize by October 2, a week ahead of the October 17 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Youngstown'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° | 33° | 44° | 55° | 64° | 70° | 71° | 67° | 58° | 46° | 36° |
The curve peaks near 71°F — comfortable-water months here usually involve a heater or a solar cover.
