"Vermont's western shoreline and the sixth-largest natural lake in the contiguous US — 120 miles long with the Adirondacks on the NY shore and the Greens on the VT shore. Burlington's waterfront is the urban heart; the Champlain Islands are quieter and more rural. Has sturgeon. (Possibly Champ, too.)"
Seasonal pattern
When does Lake Champlain warm up?
Lake Champlain is deep (max depth 400ft) and carries significant thermal inertia, so it warms slowly — surface temperatures typically don't reach comfortable swimming range until late June or early July. Spring-fed or alpine lakes stay cooler all summer. The live forecast above shows current conditions.
