Last updated: July 25, 2026 · dates · water temp

Each 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.

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.
