Little Rock Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Little Rock 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.
The bar compresses Little Rock's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 24–April 14 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 29. Wherever the today marker sits, the nearest color change is your next appointment.
The Little Rock pool calendar
Opening — target March 31
Target March 31; the practical window runs March 24–April 14, and the 7-day mean crosses the 61°F threshold around April 14. Cold-water starts are the cheap ones.
Closing — deadline October 29
The window opens October 19 once water leaves the algae zone; the model deadline is October 29, a week ahead of the November 10 freeze normal.
Estimated water temperature by month
This is Little Rock'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 41° | 42° | 49° | 58° | 66° | 75° | 80° | 82° | 78° | 68° | 56° | 46° |
Warmest water typically July–September (peaking near 82°F); heaters and covers shift any month up.
