Leander Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Leander'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.
The bar compresses Leander's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 2–March 23 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 16. Wherever the today marker sits, the nearest color change is your next appointment.
The Leander pool calendar
Opening — target March 9
Target March 9; the practical window runs March 2–March 23, and the 7-day mean crosses the 61°F threshold around March 23. Cold-water starts are the cheap ones.
Closing — deadline November 16
The window opens November 6 once water leaves the algae zone; the model deadline is November 16, a week ahead of the November 24 freeze normal.
Estimated water temperature by month
This is Leander'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 48° | 50° | 56° | 63° | 71° | 79° | 83° | 85° | 82° | 74° | 63° | 53° |
Warmest water typically June–September (peaking near 85°F); heaters and covers shift any month up.
