Odessa Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Odessa 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.
Odessa, TX — 171 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Odessa's swim season; the hollow teal run before it (March 7 to March 28) is when to open; the hollow amber run after is when to close, with November 6 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Odessa pool calendar
Opening — target March 14
Open by March 14 — a two-week head start on the March 28 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 6
The window opens October 27 once water leaves the algae zone; the model deadline is November 6, a week ahead of the November 16 freeze normal.
Estimated water temperature by month
This is Odessa'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 44° | 46° | 53° | 62° | 69° | 79° | 82° | 83° | 78° | 70° | 59° | 49° |
Warmest water typically June–September (peaking near 83°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with North Richland Hills's pool season and Pasadena's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
Odessa pool season FAQ
When should I open my pool in Odessa, TX?

When should I close my pool in Odessa?
The closing deadline is November 6 — late enough that the water has cooled out of the algae zone, early enough to beat Odessa's first-freeze normal by about a week. See the Odessa closing guide for the winterizing steps.

Odessa averages 171 days a year with normal highs of 80°F or better — about 6 days later than the Texas median. The Texas season index ranks all 68 covered cities by the same metric.
