Lake Clark in April: what the park service says
April is usually when the ice on Lake Clark melts, the park says, after a freeze that typically begins in November. That changeover matters, because ice conditions decide whether planes on floats or skis can land. Frost and snow stay common until early June, and mountain terrain funnels strong winds, with gusts of 30 to 50 mph not unusual.
