Quebec City summer weather runs from early June through mid-September when temperatures can vary tremendously. Daytime temperatures can reach into the 90s with high humidity, especially in July and August. Lows in the 50s are rare but not unheard of.
Budget travelers should splurge on air-conditioned rooms during July and August, but beware because rooms may have noisy window units, so bring earplugs for a better night's sleep.
Earplugs will also drown out the noise from street festivals that can go till late.
What to Pack
In addition to earplugs, pack an umbrella because there is always a possibility of rainstorms or, more likely, summer showers. Clothing made from breathable fabrics works best for humid days. At night, a light jacket and long pants are recommended.
Most importantly, pack comfortable sandals and walking shoes because the streets of Quebec City are steep and cobblestoned. Other summer must-have items include a water bottle, sunglasses, hat, and sunscreen.
Quebec City Style
Dress in Quebec City is best described as fashionable yet understated. While more casual than Montreal, the emphasis for both men and women is on the clothing of good quality and cut, especially for evening and business wear.
Business casual dress is more acceptable in Quebec City than in Montreal. Sundresses, skirts, dress shorts and lightweight pants are more comfortable here than jeans in the summer.
Baseball hats and track pants are not such a sin here as in Montreal, possibly because of a higher density of tourists, especially in summer.
