Understanding San Francisco’s Weather Patterns
San Francisco’s microclimates are legendary. While other cities may enjoy predictable seasons, the City by the Bay is famed for fog that creeps in when least expected, sunshine that breaks through for a day before retreating again, and unmistakable chill—often even in the heart of summer. Here’s what you need to know about the weather:
- Summer (June to August): Characterized by chilly mornings, persistent fog (especially in June and July), and cool afternoons; rarely hot.
- Fall (September to November): The city’s warmest and sunniest months, with crisp evenings and fewer foggy days.
- Winter (December to February): Mild temperatures, occasional rain, and increased winds.
- Spring (March to May): Breezy and bright, with wildflowers in Golden Gate Park and variable weather patterns.
Tip: Always pack layers—including a jacket—even in summer. San Francisco’s famous quote holds true: “The coldest winter I ever spent was a summer in San Francisco.”
