🇺🇸 Erie vs 🇺🇸 San Francisco

Erie on Lake Erie's southern shore is Pennsylvania's only Great Lakes city with intense lake-effect snow. The city averages over 100 inches of snow annually, making it one of the nation's snowiest. Lake Erie's shallowness means it warms and cools faster than other Great Lakes, producing extreme lake-effect events. The lake moderates summer temperatures significantly.

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.
