September Events in Sonora
September is one of the most active and exciting months of the year in Sonora, and throughout Mexico.
The intense summer heat begins to ease, monsoon storms fade, and Sonora returns to bright blue skies, warm afternoons, and some of the most enjoyable evenings of the year. It is also a month full of civic pride, cultural festivals, and religious celebrations in Sonoran towns and pueblos.
In Mexico, September is known as el mes patrio, the Month of the Homeland. Mexican Independence Day is observed on September 16, and the night before, communities across Sonora gather at their palacios municipales for one of Mexico’s most iconic traditions, El Grito de la Independencia, a collective shout of pride, identity, and history.
September also includes major feast days in the Catholic calendar, celebrated with reverence and community fiestas across Sonora. They include days for Santa Rosalía, the Virgen de Loreto, the Virgen de los Dolores, and the feast days of the archangels San Miguel, San Gabriel, and San Rafael.
And by the final week of September, the energy begins building toward one of Sonora’s most beloved celebrations, the fiestas of Magdalena de Kino, which lead into early October.
