Crescent City has a temperate climate, with highs in the mid-50s in winter and in the mid-60s in summer. Winters here are considerably rainier than in the summer months, however, with an average of 14 days of rain in December and barely any showers at all in July and August. If you plan to hike or camp in the nearby redwoods, and don’t want to deal with summer crowds, consider visiting in September or early October.
