Fort Wayne Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Fort Wayne's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Fort Wayne's swim season; the hollow teal run before it (April 24 to May 15) is when to open; the hollow amber run after is when to close, with October 6 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Fort Wayne pool calendar
Opening — target May 1
Target May 1; the practical window runs April 24–May 15, and the 7-day mean crosses the 61°F threshold around May 15. Cold-water starts are the cheap ones.
Closing — deadline October 6
Hold the cover until September 26, then winterize by October 6, a week ahead of the October 21 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Fort Wayne'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 27° | 26° | 34° | 45° | 56° | 67° | 73° | 73° | 69° | 59° | 47° | 35° |
The curve peaks near 74°F — comfortable-water months here usually involve a heater or a solar cover.
