Lubbock Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Lubbock 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.
Lubbock, TX — 152 swim days a yearEach dot on the bar is one week of Lubbock'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 22–April 12), solid teal is swim season, and hollow amber is the closing window ending October 30. The black marker is today — its position against the colors is the entire executive summary.
The Lubbock pool calendar
Opening — target March 29
Open by March 29 — a two-week head start on the April 12 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 30
Hold the cover until October 20, then winterize by October 30, a week ahead of the November 11 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Lubbock'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 42° | 44° | 49° | 59° | 66° | 76° | 80° | 82° | 76° | 68° | 56° | 46° |
Warmest water typically July–August (peaking near 82°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Longview's pool season and Mansfield's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
Lubbock pool season FAQ
When should I open my pool in Lubbock, TX?
Target March 29. That date backs off two weeks from the day Lubbock's 7-day mean temperature reaches 61°F, so you start up in cold, algae-resistant water. Work the full checklist in the Lubbock opening guide.
When should I close my pool in Lubbock?
The closing deadline is October 30 — late enough that the water has cooled out of the algae zone, early enough to beat Lubbock's first-freeze normal by about a week. See the Lubbock closing guide for the winterizing steps.

Lubbock averages 152 days a year with normal highs of 80°F or better — about 21 days later than the Texas median. The Texas season index ranks all 68 covered cities by the same metric.
