Laredo Pool Season: the Year on One Bar
Last updated: July 15, 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.
Each 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.
