Mexico City Weather

March is Mexico City's best weather month — 26°C / 79°F daily highs, 40% humidity (the year's lowest by month-average), 8 sunshine hours, and effectively no rain (10mm, 2 drizzle days). The trade-off is peak North American spring break demand. Hotels in Roma Norte and Polanco spike 20-30% from February, Pujol / Quintonil reservations require 6+ weeks lead time, and Frida Kahlo Casa Azul same-day tickets sell out by 11:00 daily. International Women's Day (March 8) brings large feminist marches to Zócalo — significant Mexican cultural event but can disrupt Centro Histórico tourism on the day. Holy Week / Semana Santa is a movable late-March or early-April event (check Catholic calendar) — if it falls in March, Mexicans take a 9-day national vacation and CDMX empties (counter-intuitively quiet, hotels actually drop 10-15%) while Cancún / Acapulco / Puerto Vallarta spike +50%.

April is the last reliably dry month before May's wet-season kickoff, and temperatures climb to the year's warmest at 27°C / 81°F daily highs. UV index hits 11 (the year's extreme peak alongside May) — sunscreen, hat, and sunglasses become genuinely mandatory rather than optional. Holy Week / Semana Santa (movable, often early-to-mid April) is the biggest variable: if it lands in April, Mexicans take a 9-day national vacation, beach destinations (Cancún, Acapulco, Puerto Vallarta) spike +50%, and Mexico City counter-intuitively empties — hotels drop 10-15%, Pujol reservations open up to 3-4 weeks ahead, museums quiet down, and the city becomes the smart contrarian pick. Children's Day on April 30 brings family events to Chapultepec — the Anthropology Museum and Chapultepec Castle host free family activities.

November is Mexico City's best weather month — 22°C / 72°F daily highs, 8°C / 46°F nights, 8 sunshine hours daily, only 2 rain days expected. It's also the city's most culturally significant week (Day of the Dead Nov 1-2), the year's most expensive hotel pricing for Nov 1-2 (hotels 2-3x normal rates, book 6+ months ahead), and the most-crowded month at major sights. Day of the Dead is genuinely worth planning a trip around — UNESCO Intangible Cultural Heritage of Humanity (2008), with three distinct experiences: (1) Mixquic cemetery night vigil (45 min south, locals visit family graves with candles and Pan de Muerto, 18:00-02:00 on Nov 1-2 — the most authentic experience), (2) Coyoacán Plaza ofrendas and Catrina face-painting (Nov 1-2 daytime, family-friendly), (3) Reforma Catrina Parade (last Saturday of October, 1,000+ costumed performers). Mexican Revolution Day on November 20 brings a smaller parade and federal museum free admission. Late November sees crowds taper and hotels return to October shoulder pricing.
