On rainy days, do not go to the mountainous areas around Chiang Mai for safety reasons. But be optimistic. The rain is beneficial in some perspective, too.

Easy-dry and breathable summer clothes are the best choices, like short-sleeve t-shirt, skirt, and shorts. Sandals are quite popular among the locals and you may do in Rome as Rome does. A pair of breathable sneakers are also advised in your luggage for possible long walk and raingear is always a must in the rainy season.
