Dress light. Very light. Don't go near anything polyester lest you live to soon regret the foot-wide patch of sweat expanding over your torso as you bake in what feels like saran wrap covering your body. Instead, opt for natural, lightweight fabrics like linen, a comfort saver on a hot and humid festival day, and consider merino wool t-shirts and tanks, which wick away sweat without damaging or discoloring the fabric.
Visiting Montreal in August? Pack:
- shorts, linen pants, short-sleeved and sleeveless shirts, tank tops, summer dresses (particularly maxi dresses which are comfortable on a warm day and yet can withstand a temperature drop in the evening)
- light cardigans (e.g., linen, merino wool), wraps, light cotton jackets, blazers, windbreakers
- long pants, jeans, leggings made with breathable material
- closed toe shoes, open-toe shoes, sandals
- sunglasses, sunscreen are a must year round; sunhat could be useful
- umbrella and/or raincoat

**Note that light showers, rain and/or snow may overlap on the same day. For example, if Month X features an average of 10 days of light showers, 10 days of heavier rain and 10 days of snowfall, that does not mean that 30 days of Month X are typically characterized by precipitation. It could mean that, on average, 10 days of Month X could feature light showers, rain and snow within a 24-hour period.
