🇺🇸 Gresham vs 🇺🇸 San Francisco

Gresham east of Portland in the Columbia River Gorge entrance has a transitional climate between the maritime Willamette Valley and the more continental Columbia River Plateau. The Gorge channels powerful east winds (called 'Gorge winds') that can reach hurricane force when pressure differences between the coast and interior build up.

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.
