Mexico Mexico City Weather in December — Climate Guide
December in Mexico City is Very Good
December is Very Good for Mexico City.
December is Mexico City's Christmas + NYE month — Posadas (traditional Christmas processions re-enacting Mary and Joseph's search for shelter) run December 16-24 with neighborhood-level processions in Coyoacán, San Ángel, and historic Centro Histórico (parishioners walk with candles and statues of Mary and Joseph, knocking on pre-arranged houses to request lodging, ending in piñata-breaking and ponche de frutas). Christmas Eve (Nochebuena, December 24) is the bigger Mexican holiday than Christmas Day — families gather for late-night dinner with bacalao (Spanish-style cod), romeritos (Mexican greens with shrimp), and Rompope (Mexican eggnog). New Year's Eve brings Reforma fireworks visible from rooftop bars in Polanco, Roma Norte, and Reforma hotels. Hotels spike +30-50% for Dec 22-Jan 2, Pujol / Quintonil have Christmas tasting menus (book 6+ weeks ahead), and Korean / Japanese year-end vacation travelers create modest demand for direct LAX / DFW transit flights.
