Mexico's Climate Zones
Mexico spans tropical coasts, high-altitude cities, northern deserts, and jungle lowlands. Mexico City at 2,240m has spring-like weather year-round (15–25°C). The Pacific and Caribbean coasts have wet (June–October) and dry (November–May) seasons. Baja California has a Mediterranean climate. Your ideal timing depends entirely on where you're going.
Dry Season (November–May): Peak Travel
The best overall period for most of Mexico. Caribbean beaches (Cancún, Playa del Carmen, Tulum) and Pacific resorts (Puerto Vallarta, Sayulita) enjoy sunny skies and warm seas. Day of the Dead celebrations (October 31–November 2) in Oaxaca and Mexico City are world-famous. Christmas and Easter are busy domestic holiday periods with higher prices.
Rainy/Hurricane Season (June–October)
Afternoon rain showers are common but usually brief. The Gulf and Caribbean coasts face hurricane risk (peak August–October). However, prices drop 30–50%, landscapes are lush green, and the Pacific coast sees excellent surfing. Mexico City and highland destinations (San Miguel de Allende, Guanajuato, Oaxaca) are pleasant with mild rain.
Best Month for Each Region
Cancún/Riviera Maya: December–April. Pacific coast: November–May. Mexico City: March–May (warm, dry, before rainy season). Oaxaca: October–November (Day of the Dead + dry season beginning). Baja California: October–November (warm seas, whale season begins). Chiapas: November–February.
Our Recommendation
Late October to November offers the magic combination: Day of the Dead, dry season beginning, whale season in Baja, and pre-peak prices. For beach holidays, January–March is reliable. Budget travelers should target June–September for mainland destinations away from the coast.
