Important Things To Do
Currency
The official currency in Mexico City, and the rest of Mexico, is the Mexican Peso.
National Languages
Mexico has many indigenous languages, although here in Mexico City (as elsewhere in the country), most of the population speaks Spanish. English is not widely spoken.
You may find that some of the staff at the top hotels speak English. But locals appreciate it when you try to use at least some common Spanish phrases when getting around.
Climate And Weather
Mexico City’s climate is subtropical. Despite the tropical latitude, the high altitude means the nights can be cold, especially in Winter. The nighttime cold is more pronounced in the countryside than in the city.
Most of the rainfall occurs in the Summertime, particularly in July and August. Spring is the warmest season but the nights can still be cold. The first rains start towards the end of Spring, in May. Autumn/Fall is quite short. Winter days are dry and pleasant but nights can get quite chilly.
