The best time of year to visit Carlsbad for camping is during the spring and fall months when the weather is mild and crowds are smaller. The summer months can be quite hot and crowded, while winter can be rainy and chilly. Fall, when the crowds thin out, is also a great time to go surfing. September and October mix the southwest, west, and northwest swells for a variety of beach breaks. That said, the weather near Carlsbad is generally mild year-round, so camping is possible at any time of the year.
