November to April (Dry Season): Peak Sunshine, Whale Watching & Monarch Butterflies
From November through April, virtually all of Mexico enjoys dry blue skies, low humidity, and comfortable daytime temperatures (22–26°C in highland cities like CDMX, Oaxaca, and San Miguel; 27–30°C on the Caribbean and Pacific coasts). This window also aligns with Mexico's premier wildlife spectacles: millions of Monarch butterflies wintering in Michoacán and Estado de México fir forests (late Nov–March), humpback and gray whales in Los Cabos, La Paz, and Puerto Vallarta (Dec–March), and whale sharks in La Paz (Nov–March).
May to October (Rainy / Green Season): Lush Landscapes, Afternoon Showers & Sargassum Notes
Mexico's rainy season (May–October) rarely means all-day rain: in highland cities (CDMX, Guadalajara, Oaxaca, Puebla), mornings and early afternoons are sunny and warm, followed by a refreshing 60-to-90-minute thunderstorm around 5:00 PM. Along the Caribbean coast (Cancún, Riviera Maya, Tulum), May–October brings warmer humidity, the Atlantic hurricane window (peak August–October), and seasonal sargassum seaweed on east-facing beaches—during summer, head to west-facing Cozumel/Isla Mujeres Playa Norte, freshwater cenotes, Bacalar, or the Pacific coast.
Major Cultural Calendar Peaks: Día de Muertos, Guelaguetza, Cervantino & Semana Santa
Four cultural dates transform Mexican travel: (1) Día de Muertos (October 31–November 2) in Oaxaca, Pátzcuaro, Janitzio, Mexico City, and San Miguel de Allende; (2) La Guelaguetza indigenous dance festival in Oaxaca (last two Mondays of July); (3) Festival Internacional Cervantino in Guanajuato (October); and (4) Semana Santa (Holy Week before Easter) when domestic beach and colonial hotel occupancy reaches 95–100%.
