🇲🇽 Mexico City vs 🇺🇸 Trenton

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.

Trenton, New Jersey's capital, on the Delaware River has a humid subtropical climate at the transition with humid continental. The Delaware River provides humidity and flooding risk while the city's industrial legacy has created heat island effects that exceed neighboring communities. Washington crossed the Delaware near here — winter weather at the river can be dramatic.
