This table is Guadalajara (Obs), station 14065, at 1,551 metres. SMN also publishes a 1991–2020 normal for Guadalajara (DGE), station 14066. They are not the same series, and this page does not average them. The University of Guadalajara keeps its own Minerva record. That is a third series, and it is not used here.

The observatory reads as a highland city: cool nights in the dry months, warmer afternoons, and the rain pushed into summer. Compare it with Tacubaya if you want to see two highland stations, and with Puerto Vallarta if you are deciding between the city and the coast.

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.

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.
