Bridgeport Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Bridgeport 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.
Bridgeport, CT — 69 swim days a yearThe bar compresses Bridgeport's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 29–May 20 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 13. Wherever the today marker sits, the nearest color change is your next appointment.
The Bridgeport pool calendar
Opening — target May 6
Target May 6; the practical window runs April 29–May 20, and the 7-day mean crosses the 61°F threshold around May 20. Cold-water starts are the cheap ones.
Closing — deadline October 13
Hold the cover until October 3, then winterize by October 13, a week ahead of the November 6 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Bridgeport'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 33° | 32° | 37° | 45° | 56° | 65° | 74° | 76° | 72° | 62° | 51° | 41° |
The curve peaks near 76°F — comfortable-water months here usually involve a heater or a solar cover.
Every station tells its own story: compare this curve with Waterbury's pool season and Danbury's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Connecticut season index.
