✈️ Flight Guide: San Francisco (SFO) → Cancun (CUN)

November ushers in cultural activities across the Yucatán Peninsula and the Riviera Maya. Early November often overlaps with Día de Muertos (Day of the Dead) observances in towns and smaller communities near Cancún, featuring altars, parades, and culinary traditions. Additionally, regional events such as music festivals, art fairs, and gastronomic showcases frequently schedule dates in November to take advantage of pleasant weather. Travelers from San Francisco International Airport (SFO) should check event calendars in Cancún, Playa del Carmen, Tulum, and Mérida when planning a November itinerary.

November sits in the shoulder season for Cancún, often offering a sweet spot of lower prices and improved weather after the summer storms. The best time to fly is mid-week (Tuesday–Thursday) and during early morning slots when air traffic is lighter and on-time performance tends to be better. Avoid Thanksgiving week if you want the lowest fares and smallest crowds — if traveling during the holiday, book well in advance and consider red-eye departures for smoother travel.
