Elizabethtown, KY — 103 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Elizabethtown's swim season; the hollow teal run before it (April 12 to May 3) is when to open; the hollow amber run after is when to close, with October 14 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Elizabethtown pool calendar
Opening — target April 19
Open by April 19 — a two-week head start on the May 3 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 14
Hold the cover until October 4, then winterize by October 14, a week ahead of the October 25 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Elizabethtown'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 34° | 34° | 42° | 51° | 61° | 69° | 75° | 76° | 72° | 62° | 51° | 40° |
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 Bowling Green's pool season and Lexington's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Kentucky season index.
