🇬🇧 Edinburgh vs 🇺🇸 San Francisco

Edinburgh's topography dramatically shapes its weather. The city is built on volcanic hills including Castle Rock and Arthur's Seat. The Firth of Forth to the north and the North Sea to the east mean persistent easterly winds (the 'haar') that roll fog in from the sea, sometimes covering the city for days.

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.
