Syracuse Pool Season: the Year on One Bar
Last updated: July 25, 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.
Syracuse, NY — 56 swim days a yearReading 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.
Every station tells its own story: compare this curve with Staten Island's pool season and Utica's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the New York season index.
Syracuse pool season FAQ
When should I open my pool in Syracuse, NY?
The site model recommends opening by May 11 — about two weeks before Syracuse's 7-day mean temperature crosses 61°F, while the water is still too cold for algae. The step-by-step sequence is in the Syracuse opening guide.
When should I close my pool in Syracuse?
Winterize by September 30. The model holds the deadline a week ahead of Syracuse's NOAA 50% first-freeze date, so the plumbing is protected before the first hard night. The full sequence is in the Syracuse closing guide.
How long is the swim season in Syracuse?
Syracuse averages 56 days a year with normal highs of 80°F or better — about 5 days later than the New York median. The New York season index ranks all 16 covered cities by the same metric.
How warm does pool water get in Syracuse?
An unheated pool near Syracuse typically peaks around 72°F in high summer and bottoms out near 24°F in winter, never quite reaching the 78°F comfort line without a heater or solar cover. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
