Killeen Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Killeen'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 Killeen's swim season; the hollow teal run before it (March 5 to March 26) is when to open; the hollow amber run after is when to close, with November 10 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Killeen pool calendar
Opening — target March 12
Open by March 12 — a two-week head start on the March 26 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 10
Hold the cover until November 4, then winterize by November 10, a week ahead of the November 17 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Killeen'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 48° | 50° | 55° | 63° | 69° | 78° | 83° | 85° | 82° | 73° | 62° | 53° |
Warmest water typically June–September (peaking near 85°F); heaters and covers shift any month up.
