What to expect in May

🎯 Open terraces and outdoor markets — best season for al fresco dining Spring marks the start of the good season in Oaxaca. Temperatures rise (30°C) and tourists have not yet arrived en masse. Expect rain on 28% of days — a light raincoat in the bag is recommended. A good balance between weather and crowds, even if February (9.4/10) remains theoretically better.
