Traveller notes on Guadalajara in October
Other months in Guadalajara
Forum posters describe June as the start of Guadalajara's rainy season, but note the pattern is genuinely manageable: rain hardly ever falls in the morning, so outdoor plans scheduled early in the day tend to go untouched, and afternoon or evening downpours come down hard but rarely last for hours. Posters do flag real traffic disruption during rainy season, especially between 4 and 7pm, when flash flooding can affect underpasses across the city. Posters consistently recommend carrying an umbrella and, for those sensitive to bites, some mosquito protection given the wetter conditions. Posters note temperatures drop noticeably and pleasantly right after a downpour. Posters generally rate June as warm and rain-prone but easy to plan around, mornings and evenings the reliably pleasant stretches of the day.
December is among Guadalajara's coolest months, and the forum's framing is all about the daily swing: comfortable by day at around 25°C, then dropping away sharply once the sun goes — the record puts nights near 12°C. Pack for both ends, light fabrics for the afternoon and a proper jumper or jacket for the evening. Rain is essentially finished by December, two days across the month. One practical warning if the trip covers Christmas itself: a great deal closes for the key days in Mexico.
