Summer (June-August): Warm temperatures (20-26°C), longer daylight hours, and countless outdoor activities. Festivals, street performances, and outdoor dining create vibrant atmosphere. Popular season with higher prices and larger crowds.
Fall (September-October): Mild weather, stunning foliage colors on Mount Royal and parks, and fewer tourists. Perfect for outdoor exploration and photography. Early September offers summer benefits with declining crowds.
Spring (April-May): Mild warming weather (10-15°C), spring flowers bloom, and locals emerge from winter. Easter celebrations and spring festivals attract visitors. Weather remains unpredictable with occasional rain.
Winter (November-March): Snowy landscapes create magical atmosphere; temperatures drop to -10°C. Winter sports, ice skating, and holiday decorations appeal to some visitors. High heating bills in accommodations reflect extreme cold.
Recommendation: June-September offers optimal weather and maximum attractions. September-October provides best balance of weather and fewer crowds.
