Montreal's fall weather forecast is out and terrasse season might last longer than usual

The official arrival of fall is still a couple of weeks away, but Montreal's upcoming weather changes are already coming into focus. The Weather Network just released its 2025 fall forecast for different parts of Canada, and it hints at a season that could play out differently than what we're used to.

According to meteorologists, Quebec got an early taste of autumn during late August and early September, when temperatures dropped off sharply after weeks of summer heat. But for the core of the season — from mid-September through October — Montreal and much of the province are expected to stay on the mild side.

Here's when the first snowfall of the season could hit Montreal and other parts of Quebec

Warm weather is in the cards for the beginning of October in Quebec, but don’t get too used to summer-like days. Temperatures are expected to drop abruptly — and soon. At least, that's what some forecasts suggest, leaving little time before the first snowfall ushers in lasting cold throughout the province, including the Greater Montreal area.

In addition to a discouraging forecast from the Farmers' Almanac, which predicts plenty of rain, wind and early frosts for this first full month of autumn, MétéoMédia says lasting cold generally sets in throughout Quebec as of October 21, with maximum temperatures below 10 C and minimums below freezing.

The Quebec weather forecast warns of more tornadoes and 'violent' storms this summer

Late Monday afternoon, Quebec was hit with its first tornado of the year, damaging homes in the Montérégie region, just 70 kilometres west of Montreal. Meanwhile, Montreal was under a severe thunderstorm watch, as strong winds gusted and rain poured, ultimately leaving tens of thousands of people without power.

Unfortunately, according to the Quebec forecast, this isn't the last we'll see of this sort of weather in the next few months — and it's all thanks to two climate patterns called El Niño and La Niña. If you're reading this El Niño and La Niña, that "thanks" was sarcastic.

Montreal Weather Will Be Springlike This Week But Not For Long

Quebec could see a week of weather extremes — from balmy to biting — with a forecast that differs from the usual March outlook. A broad low-pressure system is set to bring a mix of unseasonably mild temperatures and rain, followed by a sharp drop in temperatures across the province. The unusual weather pattern has implications for everything from daily commutes to rapidly melting snow.

The week will start with a semblance of spring as temperatures climb, offering a break from the winter chill. However, the mild weather is expected to accelerate snowmelt, leading to "water ponding" in some areas, which may require immediate attention to prevent flooding and property damage, according to a special weather statement from Environment Canada.

Montreal Weather In February Will Be Bitterly Cold & Snow-Packed, According To Forecasts

Montreal's upcoming weather forecast might have you seriously considering hibernation as a viable option. A cold front is on its way, and with it, temperatures are expected to take a dive, making the inside of your freezer seem downright cozy in comparison.

The dreaded polar vortex is back, pulling temperatures across a significant part of the continent down 10 to 15 degrees below normal. For Montreal, the cold that has already made its icy entrance is here to stay, with a -15°C day — and taste of Arctic-like chill — already recorded on January 19. Other parts of the province are bracing for a wind chill factor that could reach a bone-chilling -45 to -50°C in some areas.

Montreal Weather Is Getting A Snowy Blast After All The Rain — Here's How Much To Expect

Montreal and surrounding areas are in the grips of a major storm, thanks to an unpredictable weather system. Originating from Western Canada, the system is expected to bring a mix of heavy rain and snow. The dramatic shift in weather could pose a challenge for commuters and city services due to rapidly changing conditions.

Montreal's meteorological mood swing

A variable weather system made its way into Quebec through Abitibi-Témiscamingue on Sunday, bringing high amounts of rain. Temperatures were above freezing in Montreal, causing precipitation to start as drizzle. Accumulation in the city ranged between five and 10 millimetres.

Montreal Could Get Hit With Another Winter Storm This Weekend

Montreal, still reeling from a heavy snowfall, is now bracing for another potential winter storm this weekend. The city and surrounding regions in Quebec are poised for a mix of weather conditions, starting with milder temperatures and evolving into substantial rain and snow.

Météomédia forecasts the storm will hit Quebec from Sunday, December 10, to Monday, December 11. Thanks to a jet stream – a high-speed air current in the atmosphere — taking a more northerly path, the southern part of Quebec, including Montreal, will first get milder, warmer air, leading to rainfall. But as the storm moves on, there's a chance for it to turn into snow, especially later in the storm.
