Best time to visit Mexico City from the UK

October through April is the dry season and best for British visitors. Temperatures in Mexico City are mild at 15C to 23C year-round due to the altitude of 2,240 metres. March and April are the warmest dry-season months. May through September is the wet season with afternoon rains, though mornings are usually clear. Dia de Muertos (Day of the Dead) in late October to early November is a spectacular cultural experience.

Airport and Transit Connectivity

Mexico City International Airport (MEX), also called Benito Juarez Airport, is about 5 kilometers from the Historic centre. The airport has 4G throughout its two terminals. The Mexico City metro Line 5 (yellow) connects the airport to the metro network.

Uber operates from the airport but requires booking from the official Uber zone in the terminals. Taxis from authorized airport stands have fixed rates to different zones. The Felipe Angeles International Airport (NLU) north of the city connects via the Tren Suburbano and shuttle buses.

Uber, DiDi, and Cabify all operate in Mexico City and need live data. The CDMX Mi Movilidad transit app for real-time metro and bus info needs a data connection. British travellers arriving here should check they have their data active before leaving the arrivals hall.
