Bryan Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Bryan's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
Bryan, TX — 185 swim days a yearEach dot on the bar is one week of Bryan'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 19–March 12), solid teal is swim season, and hollow amber is the closing window ending November 23. The black marker is today — its position against the colors is the entire executive summary.
The Bryan pool calendar
Opening — target February 26
Target February 26; the practical window runs February 19–March 12, and the 7-day mean crosses the 61°F threshold around March 12. Cold-water starts are the cheap ones.
Closing — deadline November 23
The window opens November 13 once water leaves the algae zone; the model deadline is November 23, a week ahead of the November 30 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Bryan'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 52° | 53° | 59° | 66° | 73° | 80° | 84° | 86° | 84° | 76° | 65° | 56° |
Warmest water typically June–September (peaking near 86°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Brownsville's pool season and Carrollton's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
