Montreal Weather in October

October weather in Montreal

October feels cool, changeable and often damp. Afternoons can be pleasant for walking, but evenings turn chilly, and rain is common. The days are shorter than in September, so you'll have less daylight for long outings.

Old Montreal's streets, museums and cafés work well when showers pass through. On a dry day, walk Mount Royal for fall colour and views over the city. Skip long outdoor plans when it's wet; muddy paths and grey skies can make a hike less rewarding.

October events and crowds

Canadian Thanksgiving falls in October, and Halloween brings decorations and events around the city. Fall colour draws visitors to Mount Royal, though the city is generally quieter than in summer. With summer's peak season over, you may find better hotel rates, but prices still depend on dates and demand.

For families, the leaves and Halloween events can make a fun city break, but keep indoor sights in mind for rainy afternoons.

Tips for your visit

A rain-speckled day is a good excuse to explore the Underground City, the network of shops and walkways beneath downtown. It connects with metro stations, so you can move between stops without spending the whole day outdoors.

For Mount Royal, take the path from the Peel Street entrance if you want a direct climb toward the lookout. Wet leaves can make the route slippery, so turn back if the trail feels unsafe. October is cooler than September and milder than November, but don't count on dry weather for your whole stay.
