May is one of the best months for independent travellers in Mexico. The dry season is ending but not yet fully over, international visitor numbers are lower than April, domestic prices have normalised, and whale sharks are starting to appear off the Yucatán.

Weather

Caribbean coast: Warm (30–33°C), mostly dry still, though afternoon clouds and light rain begin appearing by the end of the month in some areas.

Pacific coast: Still dry in most areas. Puerto Vallarta begins to see the first rains in late May.

Mexico City and central highlands: Hot (27–30°C) and dry through May. The rainy season typically starts in Mexico City in late May or early June.

Yucatán interior (Mérida): Extremely hot in May — 38–42°C. Cenotes and early mornings are the strategy.

Crowds and prices

Post-spring break, post-Easter: May has the fewest international tourists of any month in the April–December window. Hotels are easier to book, prices are lower, and popular sites are less crowded than at any other point in the peak season. The trade-off is occasional heat.

Whale sharks

Whale shark aggregations off Holbox and the northern Yucatán begin in earnest in May. Numbers build through June and peak in July–August. May offers more intimate encounters with fewer tour boats in the water.

Cinco de Mayo

The date is the anniversary of Mexico’s unlikely victory over French forces at the Battle of Puebla in 1862. It’s primarily celebrated in Puebla — reenactments, parades, and festival events. In the rest of Mexico, it’s a relatively minor observance. The “major Mexican holiday” framing exists mostly in the US.

In Puebla: genuine celebrations with historical pageantry and a festival atmosphere. Worth visiting if you’re in the region.

Labour Day (1 May)

International Workers’ Day is a national holiday — some businesses close, and domestic tourist movement is active around the long weekend.

What May is good for

  • Oaxaca at its most comfortable for city exploration
  • Visiting Mérida’s museums and cultural sites (cool interiors + fewer tourists)
  • Cenote visits before the July–August crowds
  • Mexico City’s museums and food scene without European school holiday crowds
