Founded in 1542 in the Atemajac Valley, Guadalajara now anchors Mexico's third-largest metro area, home to 5.5 million people. It is the birthplace of mariachi music and sits near the agave fields that produce tequila. Its unlikely reinvention began in the 1990s, when IBM, HP and Motorola built up an electronics industry that earned the city the nickname 'Mexico's Silicon Valley'.
Guadalajara barely changes season: around 22°C most of the year.
Rain is spread through the year — about 787 mm in total, from 215 mm in July down to 0 mm in March — so no single month is a washout.
Wind is rarely an issue; most months sit between calm and a light breeze. Air quality is worth watching: August averages an AQI of 62, while March clears to 51.
Days stretch to about 13.2 hours of light in June and shrink to 10.8 in December — something to weigh if you work to a fixed timezone.
For what you're after, the best months in Guadalajara are March – June. Expect fast internet (177 Mbps) and a moderate cost of living (about €1350 a month).
