Laredo Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Laredo pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
Laredo, TX — 237 swim days a yearEach dot on the bar is one week of Laredo's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (January 17–February 7), solid teal is swim season, and hollow amber is the closing window ending December 10. The black marker is today — its position against the colors is the entire executive summary.
The Laredo pool calendar
Opening — target January 24
Target January 24; the practical window runs January 17–February 7, and the 7-day mean crosses the 61°F threshold around February 7. Cold-water starts are the cheap ones.
Closing — deadline December 10
The window opens December 2 once water leaves the algae zone; the model deadline is December 10, a week ahead of the December 17 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Laredo'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 57° | 60° | 66° | 74° | 80° | 86° | 88° | 90° | 86° | 80° | 71° | 62° |
Warmest water typically May–October (peaking near 90°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Killeen's pool season and League City's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.

Winterize by December 10. The model holds the deadline a week ahead of Laredo's NOAA 50% first-freeze date, so the plumbing is protected before the first hard night. The full sequence is in the Laredo closing guide.
