Last week reflected this Summer's age. The air was cooler, the lake temperature was off peak, and the sun wasn't up as long. Even so, most are currently hat-less, you can sorta get used to the water, and there's still plenty of sunlight. Life remains good!
Less than 2 weeks ago the water temperature of Lake Lucerne peaked at 82°F. Swimming was comfortable, falling while skiing could be painful but without the added unpleasantness of hypothermia. Last week the lake temp fell down to a more Lucerne-ish 74°F. Not freezing, but not 82°F either.
