Michoacán

Winter (December to February): This season is generally pleasant in Michoacán, with mild temperatures, making it suitable for exploring historical cities like Morelia and enjoying the local culture. However, it might not be the best time for visiting the monarch butterfly sanctuaries, which are often closed during this period.

Spring (March to May): Spring is an excellent time to visit the monarch butterfly sanctuaries as the butterflies start their migration northward. It's also a good time for exploring nature reserves, enjoying mild temperatures, and witnessing blooming landscapes.

Summer (June to August): Summers can be warm in Michoacán, especially in lower elevations. However, it's a good time for outdoor activities, visiting the coast (if you're heading to areas like Lázaro Cárdenas or Zihuatanejo), and experiencing local festivals.

Autumn (September to November): Autumn can bring occasional rainfall but also offers cooler temperatures. It's another good time to visit the monarch butterfly sanctuaries as the butterflies begin their southward migration.
