Burlington Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Burlington'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.
Each dot on the bar is one week of Burlington's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (March 30–April 20), solid teal is swim season, and hollow amber is the closing window ending October 26. The black marker is today — its position against the colors is the entire executive summary.
The Burlington pool calendar
Opening — target April 6
Target April 6; the practical window runs March 30–April 20, and the 7-day mean crosses the 61°F threshold around April 20. Cold-water starts are the cheap ones.
Closing — deadline October 26
The window opens October 16 once water leaves the algae zone; the model deadline is October 26, a week ahead of the November 9 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Burlington'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 42° | 42° | 48° | 56° | 64° | 73° | 79° | 79° | 75° | 66° | 56° | 47° |
Warmest water typically July–August (peaking near 80°F); heaters and covers shift any month up.
