Travel Tips

Altitude: Remember that Mexico City is situated at a high altitude (over 7,000 feet or 2,200 meters), which can make the weather feel cooler than the actual temperature.
Packing: Layers are key due to the temperature fluctuations. Bring a light jacket for the evenings, especially in winter.
Sunscreen: No matter the season, the high altitude means stronger UV rays, so always wear sunscreen.
