Quebec City is a year-round destination, but the sweet spot for most travelers is June through September, when highs run 22-25 degrees C and festivals fill the calendar. Winter is for the Carnaval de Quebec, and fall brings foliage and harvest season. This Quebec City weather by month guide has the underlying data; here is when to actually go. See the things to do in Quebec City guide for more detail.
Best Time to Visit Quebec City: Best Weather
June, July, and August offer the warmest, most reliable sightseeing weather. July averages a 25 degrees C high and 119 mm of rain; August a 23 degrees C high and 109 mm. Late September and early October are cooler (18 and 11 degrees C highs) but still comfortable, with the first fall color on the Plains of Abraham. Avoid November and early December, when highs sit near freezing and daylight drops below 9 hours.

Crowds peak in July and August, especially in Old Quebec between 10 a.m. and 4 p.m., and again during the two-week Carnaval de Quebec in late January and February. May and October are the quietest months with attractions fully open. For a sense of what fills the calendar, see the Quebec City events and festivals guide before you lock dates.
