Mexico Cancún Weather in March — Climate Guide
March in Cancún is very-high
March is very-high for Cancún.
March is dual-purpose: the Spring Equinox at Chichén Itzá (March 20-21) creates the famous 'descending serpent' shadow on El Castillo pyramid's north stair — a 9th-century Mayan astronomical engineering masterpiece. Tickets sell out 6+ months ahead. The other reality is Spring Break — US college students transform Hotel Zone (especially Punta Cancún clubs Coco Bongo, Mandala Beach, The City) into 4-week party chaos.
Families + honeymoon couples seeking quiet should book Playa Mujeres adult-only resorts (Excellence, TRS, Beloved) — completely separated from Spring Break chaos by 30 min drive. South Hotel Zone (Punta Nizuc, km 15-25) is calmer than Punta Cancún.
