Weather and SeasonsSpring is ideal, with daytime highs between 70 and 85°F and nights in the 50s to 60s. The lake warms enough for comfortable paddling, and trails dry out after winter rains, making cliff access safer. Wildflowers bloom, and wildlife activity peaks for birding and photography. Summer heat can push into the 90s, sending most visitors to the beach or lake. Fall brings comfortable temperatures again. Winter days are crisp and good for hiking or climbing when it's dry, though occasional rain can make rock surfaces slick. Weekend crowds pick up in spring, but weekdays stay quiet.
