Spring delivers the most comfortable conditions. Daytime temperatures range from the mid-50s to mid-70s°F, dropping to the 30s–50s°F at night. Wildflowers peak during this season, and trails are pleasant for hiking. Weekend crowds pick up during bloom season, but weekdays stay quiet. Clear nights offer strong stargazing.
Spring called 'best weather' with peak wildflower displays and fuller streams from runoff.
