Bowling Green, KY — 127 swim days a yearEach dot on the bar is one week of Bowling Green's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (April 1–April 22), solid teal is swim season, and hollow amber is the closing window ending October 23. The black marker is today — its position against the colors is the entire executive summary.

Estimated water temperature by month
This is Bowling Green'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 38° | 38° | 45° | 55° | 64° | 73° | 79° | 80° | 75° | 66° | 54° | 44° |
Warmest water typically July–August (peaking near 80°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Louisville's pool season and Elizabethtown's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Kentucky season index.
