Pearland Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Pearland 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.
Pearland, TX — 190 swim days a yearEach dot on the bar is one week of Pearland'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 4–February 25), solid teal is swim season, and hollow amber is the closing window ending December 4. The black marker is today — its position against the colors is the entire executive summary.
The Pearland pool calendar
Opening — target February 11
Open by February 11 — a two-week head start on the February 25 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline December 4
Hold the cover until November 24, then winterize by December 4, a week ahead of the December 27 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Pearland'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 55° | 57° | 62° | 68° | 74° | 82° | 84° | 85° | 83° | 77° | 68° | 60° |
Warmest water typically June–September (peaking near 85°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Pasadena's pool season and Pflugerville's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
Pearland pool season FAQ
When should I open my pool in Pearland, TX?
Open by February 11 — the model places Pearland's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Pearland opening guide has the 12-step sequence.
When should I close my pool in Pearland?
Close by December 4: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Pearland closing guide sequences the work backward from that date.
How long is the swim season in Pearland?
Pearland averages 190 days a year with normal highs of 80°F or better — about 25 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 Pearland?
An unheated pool near Pearland typically peaks around 85°F in high summer and bottoms out near 55°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.
