Is Mexico warm in September?

September can be a wonderful time to visit Mexico, particularly for travelers who prefer a quieter experience. With the summer vacation crowds dispersing, you can savor more popular destinations without the throngs of tourists.

However, along the beaches, September to mid-October is hurricane season – you’ll usually get wet weather, choppy seas and mosquitoes if not a full-on tropical storm.

Prices may drop during the “shoulder” seasons – mid-September to early November and late April to early June – and the best deals are usually available during the low season (November to March, excluding Christmas and New Year).

Festivals and events in Mexico in September

Everywhere, from the remotest Indigenous village to the most sophisticated city suburb, devotes at least one day annually to partying in Mexico.

Usually, it’s in honor of the local saint’s day, but many fiestas have pre-Christian origins, and any excuse – from harvest celebrations to the coming of the rains – will do. Here are the best festivals and events in Mexico in September.

• Independence Day (Sept 16). While Easter and Carnaval are popular, this one is more official, marking the historic day in 1810 when Manuel Hidalgo y Costilla issued the Grito (Cry of Independence) from his parish church in Dolores, now Dolores Hidalgo, Guanajuato, which is still the center of commemoration. You’ll also find the day marked in the capital with the mass recitation of the Grito in the Zócalo, followed by fireworks, music and dancing.
• Festival Internacional de Santa Lucía (end of Sept and beginning of Oct). Formerly the Festival Cultural of Monterrey’s Barrio Antiguo, showcasing local rock bands and other eclectic musicians, this festival has been reborn, having outgrown the confines of the Barrio Antiguo to become a citywide event. It’s now Mexico’s third-biggest music festival.
