Jalisco in August

October through April gives you perfect weather - sunny days around 75°F and cool nights for sleeping. December and January see the most crowds, especially around Christmas and New Year's when Mexican families vacation. March brings the Festival Internacional de Cine, turning Guadalajara into a film lover's paradise. Hotel prices spike, but the energy is incredible. Avoid May through September unless you love humidity and afternoon thunderstorms. The rain can be dramatic - streets flood within minutes. But if you don't mind getting soaked, hotel rates drop by half. Here's an insider tip: November offers the sweet spot of post-rainy season freshness without peak season crowds. The agave fields look their greenest, and you'll have restaurants to yourself.
