Packing for Guadalajara in May means dressing for 32°C days and 17°C evenings. A lightweight linen or cotton shirt with loose-fit trousers or a sundress handles the 32°C daytime heat. Evenings drop 15°C to around 17°C, a notable shift that catches underprepared visitors off guard. Pack a dedicated evening layer. For footwear, breathable walking sandals work for casual exploration, but closed-toe trainers are better for uneven surfaces in the historic centre. At 78% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.

💡

Local tip: Layers are more practical than a single heavy garment in Guadalajara. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.
