Sugar Land Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Sugar Land'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.
Sugar Land, TX — 198 swim days a yearThe bar compresses Sugar Land's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 7–February 28 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 30. Wherever the today marker sits, the nearest color change is your next appointment.
The Sugar Land pool calendar
Opening — target February 14
Open by February 14 — a two-week head start on the February 28 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 30
Hold the cover until November 20, then winterize by November 30, a week ahead of the December 13 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Sugar Land'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 54° | 55° | 61° | 67° | 74° | 81° | 84° | 86° | 83° | 77° | 67° | 58° |
Warmest water typically June–September (peaking near 86°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Spring's pool season and Temple's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
