Tyler Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
Tyler's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
Tyler, TX — 164 swim days a yearThe bar compresses Tyler's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 1–March 22 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 12. Wherever the today marker sits, the nearest color change is your next appointment.
The Tyler pool calendar
Opening — target March 8
Open by March 8 — a two-week head start on the March 22 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 12
The window opens November 2 once water leaves the algae zone; the model deadline is November 12, a week ahead of the November 21 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Tyler'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 48° | 50° | 56° | 63° | 70° | 78° | 82° | 84° | 81° | 72° | 62° | 52° |
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 The Woodlands's pool season and Victoria's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
