Wichita Falls, TX — 159 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Wichita Falls's swim season; the hollow teal run before it (March 18 to April 8) is when to open; the hollow amber run after is when to close, with November 2 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Wichita Falls pool calendar
Opening — target March 25
Open by March 25 — a two-week head start on the April 8 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 2
The window opens October 25 once water leaves the algae zone; the model deadline is November 2, a week ahead of the November 9 freeze normal.
Estimated water temperature by month
This is Wichita Falls'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 42° | 44° | 51° | 59° | 67° | 77° | 83° | 85° | 80° | 70° | 58° | 47° |
Warmest water typically July–September (peaking near 85°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Waco's pool season and Abilene's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
