San Francisco's summer weather is famously cool, windy, and foggy, a stark contrast to typical summer expectations. This unique climate is primarily due to the city's location near the Pacific Ocean, which significantly influences the Bay Area's weather patterns. The Financial Times notes that San Francisco only enjoys about two weeks of truly perfect weather each summer. During these brief, sunny periods, places like Golden Gate Park become incredibly lively, attracting locals and tourists for picnics and social gatherings.
