San Clemente in December

April through October brings the best weather, but each season has its personality. Spring offers the most consistent surf and fewer crowds. The marine layer burns off earlier, giving you more sunshine. Summer means peak season everything — packed beaches, higher prices, and traffic on PCH. But the water warms up to actually swimmable temperatures, and the town comes alive with festivals and outdoor concerts. Fall might be the secret sweet spot. September and October deliver warm days, smaller crowds, and some of the year's best surf. The Santa Ana winds can make things hot and dry, but they also create those crystal-clear days when you can see Catalina Island. Winter isn't written off entirely. The storms bring bigger swells for experienced surfers, and hotel rates drop significantly. Just pack layers — morning fog can keep things cool until noon.
