Beaumont Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Beaumont 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.
Beaumont, TX — 180 swim days a yearEach dot on the bar is one week of Beaumont's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (February 14–March 7), solid teal is swim season, and hollow amber is the closing window ending November 25. The black marker is today — its position against the colors is the entire executive summary.
The Beaumont pool calendar
Opening — target February 21
Open by February 21 — a two-week head start on the March 7 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 25
The window opens November 15 once water leaves the algae zone; the model deadline is November 25, a week ahead of the December 4 freeze normal.
Estimated water temperature by month
This is Beaumont'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 53° | 54° | 60° | 66° | 73° | 80° | 83° | 84° | 82° | 75° | 66° | 57° |
Warmest water typically June–September (peaking near 84°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Baytown's pool season and Brownsville's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
Beaumont pool season FAQ
When should I open my pool in Beaumont, TX?
Open by February 21 — the model places Beaumont's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Beaumont opening guide has the 12-step sequence.
When should I close my pool in Beaumont?
Close by November 25: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Beaumont closing guide sequences the work backward from that date.
How long is the swim season in Beaumont?
Beaumont averages 180 days a year with normal highs of 80°F or better — about 15 days earlier than the Texas median. The Texas season index ranks all 68 covered cities by the same metric.
How warm does pool water get in Beaumont?
An unheated pool near Beaumont typically peaks around 84°F in high summer and bottoms out near 53°F in winter, spending roughly 4 months at or above the 78°F comfort line most swimmers prefer. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
