Syracuse Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Syracuse 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 Syracuse's swim season; the hollow teal run before it (May 4 to May 25) is when to open; the hollow amber run after is when to close, with September 30 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Syracuse pool calendar
Opening — target May 11
Open by May 11 — a two-week head start on the May 25 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline September 30
The window opens September 20 once water leaves the algae zone; the model deadline is September 30, a week ahead of the October 19 freeze normal.
Estimated water temperature by month
This is Syracuse'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 26° | 24° | 30° | 40° | 53° | 63° | 70° | 72° | 67° | 57° | 46° | 35° |
The curve peaks near 72°F — comfortable-water months here usually involve a heater or a solar cover.
