All Months
San Carlos shines from April through October, when the Peninsula's famous microclimates work in your favor. Summer mornings start cool and foggy, then burn off to reveal those perfect 75-degree afternoons that make California real estate so expensive. The marina comes alive during these months — weekend sailors, waterfront dining, kids learning to windsurf. But here's what locals know: September and October offer the best weather, after the summer fog pattern breaks down. Winter brings rain and temperatures in the 50s, which isn't terrible but kills the outdoor scene that makes this place special. Spring wildflowers bloom in the hills around March, though you'll need to hike up to Crystal Springs Trail to see them.
