Puebla in December

October through April gives you perfect weather — sunny days around 75°F and cool nights that make walking a pleasure. December and January can get chilly after dark, so pack a jacket. Cinco de Mayo (May 5th) is huge here since the holiday commemorates a local battle victory. The city throws a massive festival with parades, concerts, and enough mole to feed an army. Book accommodations months ahead if you're coming for the party. Avoid July and August unless you love rain. The rainy season dumps water on the city most afternoons, though mornings usually stay clear. September marks the chile en nogada season, so food lovers might brave the occasional downpour. Easter week brings Mexican families on vacation, driving up prices and crowds. But the processions and religious ceremonies are spectacular if you don't mind sharing the streets.
