🇺🇸 Atlanta vs 🇲🇽 Mexico City

Atlanta at 1,050 feet elevation has a humid subtropical climate modified by its inland and elevated position. The city sits on the Piedmont Plateau, giving it slightly cooler summers than coastal Georgia. However, the urban heat island from rapid development is significant. Ice storms are Atlanta's signature weather threat — thin glazes of freezing rain paralyze this car-dependent city.

Subtropical highland — mild year-round due to altitude, distinct wet season

Mexico City's high altitude (7,350 ft/2,240m) keeps temperatures surprisingly mild year-round. Days are typically 65–75°F; nights cool significantly. The rainy season (May–October) brings afternoon thunderstorms. Air quality is a year-round concern due to the enclosed valley.
