Texarkana Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Texarkana 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.
Texarkana, TX — 152 swim days a yearEach dot on the bar is one week of Texarkana's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (March 18–April 8), solid teal is swim season, and hollow amber is the closing window ending November 4. The black marker is today — its position against the colors is the entire executive summary.
The Texarkana pool calendar
Opening — target March 25
Open by March 25 — a two-week head start on the April 8 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 4
The window opens October 25 once water leaves the algae zone; the model deadline is November 4, a week ahead of the November 17 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Texarkana'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 44° | 45° | 52° | 60° | 68° | 77° | 82° | 84° | 80° | 71° | 59° | 49° |
Warmest water typically July–September (peaking near 84°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Temple's pool season and The Woodlands's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
Texarkana pool season FAQ
When should I open my pool in Texarkana, TX?
Target March 25. That date backs off two weeks from the day Texarkana's 7-day mean temperature reaches 61°F, so you start up in cold, algae-resistant water. Work the full checklist in the Texarkana opening guide.
When should I close my pool in Texarkana?
The closing deadline is November 4 — late enough that the water has cooled out of the algae zone, early enough to beat Texarkana's first-freeze normal by about a week. See the Texarkana closing guide for the winterizing steps.

Texarkana averages 152 days a year with normal highs of 80°F or better — about 17 days later than the Texas median. The Texas season index ranks all 68 covered cities by the same metric.
