"The crown jewel of the Idaho Panhandle — surrounded by forested mountains, with the downtown waterfront of Coeur d'Alene anchoring the north end. Deep, clear, cold even in summer. National Geographic has named it one of America's most beautiful lakes multiple times."
Seasonal pattern
When does Lake Coeur d'Alene warm up?
Lake Coeur d'Alene is deep (max depth 215ft) 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.
