The Woodlands Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
The Woodlands'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 The Woodlands's swim season; the hollow teal run before it (February 12 to March 5) is when to open; the hollow amber run after is when to close, with November 24 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The The Woodlands pool calendar
Opening — target February 19
Target February 19; the practical window runs February 12–March 5, and the 7-day mean crosses the 61°F threshold around March 5. Cold-water starts are the cheap ones.
Closing — deadline November 24
The window opens November 14 once water leaves the algae zone; the model deadline is November 24, a week ahead of the December 3 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on The Woodlands's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.

| 53° | 55° | 61° | 67° | 73° | 81° | 84° | 85° | 83° | 76° | 65° | 57° |
Warmest water typically June–September (peaking near 85°F); heaters and covers shift any month up.
