Near the ocean, temperatures in Santa Monica hardly fluctuate at all, resting at a balmy 64 degrees in January and an ocean-cooled 71 in September. But inland, summer through mid-autumn can top 100 degrees, compounded by the concrete-jungle effect. August can bring rain and humidity, while September is typically warmer than June. Shoulder seasons in the spring and fall bring the most moisture, with February being the rainiest month.
During the high season, June through August, tourists and locals flock to the beaches, cafés, and shops. The Santa Monica Pier stays open year-round, but its nine-story Ferris wheel, roller coaster, old-fashioned carousel, and aquarium get mobbed in the summer.
Even if you go during the low season, like late fall or winter, there’s a better-than-good chance that you’ll have a clear view of Santa Monica’s famous sunsets, best caught where Route 66 ends, on the corner of Ocean Avenue and Santa Monica Boulevard.
