Irving Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Irving'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.
Irving, TX — 161 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Irving's swim season; the hollow teal run before it (March 5 to March 26) is when to open; the hollow amber run after is when to close, with November 12 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Irving pool calendar
Opening — target March 12
Target March 12; the practical window runs March 5–March 26, and the 7-day mean crosses the 61°F threshold around March 26. Cold-water starts are the cheap ones.
Closing — deadline November 12
Hold the cover until November 2, then winterize by November 12, a week ahead of the November 24 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Irving'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 46° | 48° | 55° | 63° | 70° | 79° | 84° | 86° | 82° | 73° | 62° | 52° |
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 Houston's pool season and Killeen's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.

When should I close my pool in Irving?
Close by November 12: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Irving closing guide sequences the work backward from that date.
How long is the swim season in Irving?
Irving averages 161 days a year with normal highs of 80°F or better — about 4 days later than the Texas median. The Texas season index ranks all 68 covered cities by the same metric.
