People expect Mérida's heat to peak in summer. It peaks in May, at an average high of 38°C (100°F), before the rains arrive. The Yucatán never really cools off, so the job is staying cool, dry and bite-free, not packing layers.

Loose, light cotton and linen. Men often wear the guayabera shirt, and many local women wear the embroidered huipil. Shorts are fine in town, but people dress a bit smarter in the evening on Paseo de Montejo.
What plugs does Mérida use?
Mexico uses type A and B plugs at 127V. US and Canadian devices plug straight in. Others need an adapter with US plugs and gear that handles 127V.
