Dallas Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Dallas'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 Dallas's swim season; the hollow teal run before it (February 28 to March 21) is when to open; the hollow amber run after is when to close, with November 16 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Dallas pool calendar
Opening — target March 7
Target March 7; the practical window runs February 28–March 21, and the 7-day mean crosses the 61°F threshold around March 21. Cold-water starts are the cheap ones.
Closing — deadline November 16
Hold the cover until November 6, then winterize by November 16, a week ahead of the November 29 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Dallas'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 48° | 50° | 56° | 64° | 71° | 80° | 86° | 88° | 84° | 75° | 63° | 53° |
Warmest water typically June–September (peaking near 88°F); heaters and covers shift any month up.
