Wichita Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
Wichita'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.
Wichita, KS — 125 swim days a yearEach dot on the bar is one week of Wichita'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 10–May 1), solid teal is swim season, and hollow amber is the closing window ending October 21. The black marker is today — its position against the colors is the entire executive summary.
The Wichita pool calendar
Opening — target April 17
Open by April 17 — a two-week head start on the May 1 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 21
The window opens October 11 once water leaves the algae zone; the model deadline is October 21, a week ahead of the October 29 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Wichita'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° | 35° | 43° | 53° | 62° | 73° | 80° | 81° | 76° | 65° | 52° | 40° |
Warmest water typically July–August (peaking near 82°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Topeka's pool season and Kansas City's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Kansas season index.
