Dalton Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Dalton'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.
The bar compresses Dalton's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 29–April 19 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 28. Wherever the today marker sits, the nearest color change is your next appointment.
The Dalton pool calendar
Opening — target April 5
Target April 5; the practical window runs March 29–April 19, and the 7-day mean crosses the 61°F threshold around April 19. Cold-water starts are the cheap ones.
Closing — deadline October 28
Hold the cover until October 18, then winterize by October 28, a week ahead of the November 4 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Dalton'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 42° | 42° | 49° | 57° | 65° | 73° | 78° | 79° | 77° | 67° | 56° | 47° |
Warmest water typically July–August (peaking near 79°F); heaters and covers shift any month up.
