Mexico does not have one climate, and this page does not pretend it does. The table is the Tacubaya observatory in Mexico City, station 9048, at 2,308.6 metres, from the Servicio Meteorológico Nacional's 1991–2020 normal issued on 6 November 2026. It describes the central highlands. Cancún, Cabo San Lucas, Puerto Vallarta, and Guadalajara have their own stations.
Read the city sheet for the coast you are actually flying to. A dry month at Tacubaya can sit inside hurricane season on the Caribbean, and Cabo's late-summer rain is a different pattern again. This page does not name a best month. The station numbers are published so you can choose.
Month by month
The highest average daily high is 27.5°C in April. The lowest average daily low is 8.3°C in January. The heaviest month in the water column is August at 175.6 mm, and the lightest is December at 5 mm. These sentences only restate the table. They are not a ranking of the best month to go.

The facts, in sentences

The IEC world-plugs list shows Mexico at 127 volts and 60 hertz, with plug type A and B.

Driving side
Article 109 of the federal highway regulation, as published in the Diario Oficial on 22 November 2012, says vehicles are to be driven in the right-hand lane of a federal highway, except when overtaking, when the road is too narrow for two lanes, when the right side is blocked, on the three-lane case the article describes, or on a one-way road. This is the federal highway rule, not a city bylaw.

Tap water
CDC's traveler page for Mexico, last reviewed 3 September 2026, does not say whether tap water is safe or unsafe. It says food and water standards vary by destination and by what you are doing, and it points readers to CDC's food and water precautions. This page does not turn that into medical advice.

Currency
ISO 4217 lists the currency name Mexican Peso and the code MXN for Mexico.

Time zone
The time-zone law (last reform published 29 November 2022) sets four zones by meridian: Centro at 90° west for most of the country, Pacífico at 105° west for Baja California Sur, Nayarit except the municipality of Bahía de Banderas, Sinaloa, and Sonora, Noroeste at 120° west for Baja California, and Sureste at 75° west for Quintana Roo. IANA's zone1970.tab names the zones used on the city sheets. The comment column of that file is quoted only where it names a place.

Tipping
Mexico's consumer protection agency, Profeco, says tipping is voluntary. No establishment can require it or add it without telling you first. Profeco does not publish a customary percentage, so this page does not invent one.

Entry requirements
This is the Mexican government's page on who must apply for a visa. We do not copy that list. Instituto Nacional de Migración: Official entry requirements. Checked 14 November 2026. We do not rewrite the rule.
