Binghamton Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Binghamton 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.
Binghamton, NY — 0 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Binghamton's swim season; the hollow teal run before it (May 13 to June 3) is when to open; the hollow amber run after is when to close, with September 23 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Binghamton pool calendar
Opening — target May 20
Open by May 20 — a two-week head start on the June 3 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline September 23
Hold the cover until September 13, then winterize by September 23, a week ahead of the October 11 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Binghamton's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 24° | 23° | 28° | 39° | 51° | 61° | 68° | 69° | 64° | 54° | 43° | 33° |
The curve peaks near 69°F — comfortable-water months here usually involve a heater or a solar cover.
Every station tells its own story: compare this curve with Albany's pool season and Bronx's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the New York season index.
Binghamton pool season FAQ
When should I open my pool in Binghamton, NY?
Open by May 20 — the model places Binghamton's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Binghamton opening guide has the 12-step sequence.
When should I close my pool in Binghamton?
Close by September 23: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Binghamton closing guide sequences the work backward from that date.
How long is the swim season in Binghamton?
Binghamton averages 0 days a year with normal highs of 80°F or better — about 14 days later than the New York median. The New York season index ranks all 16 covered cities by the same metric.
