Waco Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Waco's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
The bar compresses Waco's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 7–March 28 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 13. Wherever the today marker sits, the nearest color change is your next appointment.
The Waco pool calendar
Opening — target March 14
Open by March 14 — a two-week head start on the March 28 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 13
Hold the cover until November 4, then winterize by November 13, a week ahead of the November 20 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Waco'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 47° | 49° | 55° | 62° | 69° | 78° | 83° | 86° | 82° | 73° | 62° | 53° |
Warmest water typically June–September (peaking near 86°F); heaters and covers shift any month up.
