When to go · Mexico City, Mexico
Best time to visit Mexico City
The sweet spot is April, March and May — averages 19°C, only 2 rainy days, moderate crowds.
March - May, October - December
Mexico City sits at 2,240m altitude - this moderates the tropical latitude and creates a pleasant year-round climate (16-26 degrees C). March-May is dry season and the warmest period before the rains. June-September is rainy season: intense afternoon thunderstorms (usually 3-6pm) clear by evening, leaving the air fresh. October-December is the finest season: dry, clear, the festivals of Dia de los Muertos (Nov 1-2) fill every neighborhood with marigolds and sugar skulls - the most atmospheric week in the Mexican calendar. The altitude affects non-acclimatized visitors: take it easy on day 1, drink extra water, and expect reduced alcohol tolerance.
