San Miguel de Allende in October

October through April offers perfect weather – sunny days around 75°F and cool nights that might require a light jacket. This is peak season, so expect higher prices and crowds, especially around Christmas and Easter. January and February are ideal if you hate heat. Mornings can be chilly (40s), but afternoons are perfect for walking around. The jacaranda trees bloom in March, turning the city purple. May gets hot and dusty before the rains arrive. June through September brings daily afternoon thunderstorms that clear the air but make outdoor dining tricky. Hotels drop their rates significantly during rainy season. Avoid major Mexican holidays unless you book way ahead. Día de los Muertos (November 1-2) transforms the city, but finding accommodation becomes nearly impossible. Semana Santa (Easter week) brings Mexican families, making it loud but culturally rich. The Festival de Música de Cámara in August attracts classical music lovers despite the rain. And the film festival in July offers indoor entertainment when the weather doesn't cooperate.
