Montreal June Weather: What to Wear
Think spring the first half of the month: pants, shorts and skirts are fine, but always have a cardigan, jacket or shawl nearby for when things cool by sundown.
And think humid summer for the second half of June: in other words, AVOID cheap polyester at all costs unless you like the idea of being covered in the equivalent of saran wrap under the sun.
Instead, opt for lightweight fabrics like linen, a comfort saver on a hot and humid festival day, and consider lightweight merino wool t-shirts and tanks which wick away sweat and prevent it from damaging or discoloring the fabric.
Visiting Montreal in June? 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, silk, 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
Montreal summer heat is of the humid variety. So no matter what the mercury claims the temperature is, you can be guaranteed it feels hotter if the humidity factor is high. However, June humidity typically doesn't reach epic levels until the last two weeks of June.

Have mid-length to long hair? Tie it up. Put it in a bun. Just get it off your neck. And use humidity-resistant hairspray with reckless abandon. It makes the difference between looking polished and having a brillo pad form on your head. Shorter hairdos should do fine with a bit of gel or humidity-resistant hairspray.
The best materials to wear in high humidity weather include fine gauge merino wool, linen, and tencel (aka lyocell). Silk is tricky because yes, it's breathable and light, but if sweat does get on it, it shows in a bad way (crotch rot, anyone). Consider avoiding tight silk pants and blouses, opting for airy, drapey tops and bottoms instead.
June in Montreal is incredible. Outdoor festivals and street fairs are happening every week. Must-see events include beer fest Mondial de la Bière, everything happening during Grand Prix Weekend, Les Francofolies, La Fête Nationale, and the Montreal Jazz Festival.
Locals partake in Montreal's summer festival season just as much as travelers. Weekends are spent lingering in major parks like Parc La Fontaine and Parc du Mont-Royal, especially during the Tam Tams. Whether biking the Lachine Canal, spending the day at Montreal's public markets or shopping in Chinatown, by sunset, night owls come out for their late night food fixes.

**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.
