🇺🇸 Berkeley vs 🇺🇸 San Francisco

Berkeley's climate spans a dramatic range from foggy, cool flatlands to warm, sunny hill neighborhoods. The bay provides consistent marine cooling in the flatlands, while the Berkeley Hills create a rain shadow pattern and frequently sit above the fog layer. Mark Twain's famous quote 'The coldest winter I ever spent was a summer in San Francisco' could apply equally to Berkeley's bayside neighborhoods.

San Francisco's climate is shaped by its position on a peninsula surrounded by the Pacific Ocean and San Francisco Bay. The coastal fog (Karl the Fog) rolls in through the Golden Gate each summer afternoon, keeping temperatures mild year-round. The city has dramatically different microclimates — the Sunset District fog-bound while the Mission basks in sun on the same day.
