As the nights get colder and the leaves begin to fall from the trees, it is becoming clearer and clearer that summer is almost officially over. While sun-lovers embrace every last second of that afternoon warmth, and fall-lovers get excited for the season of pumpkin-spice and woolly sweaters, there is one thing everybody can look forward to together, Halloween! Fortunately for the more organized among us, the Old Farmer’s Almanac has released their predictions for Canada's weather on October 31, and here’s what you need to know!

The Old Farmer’s Almanac is one of Canada’s most trusty sources for long-term weather predictions, and thankfully they are now sharing the forecast for the end of next month. If you want to beat the crowds and get your Halloween 2019 costume sorted in advance, it is worth checking the forecast for your area, just in case you’ll need to wear a snowsuit under your outfit!

To help you get prepared, we’ve rounded up the long-range forecasts for across the country, breaking down what the weather will be like on and around October 31.

Atlantic Canada: 

The Old Farmer’s Almanac has included Newfoundland, Nova Scotia, Prince Edward Island and New Brunswick for this prediction.

Currently, the website is predicting average temperatures of 7.5 degrees for Halloween-month, with that being just 1 degree below the typical average temperature for this time of year.

If you’re planning on trick-or-treating, you might want to take an umbrella out with you, as there is predicted rain in the area across the week. That said, the rain is expected to be pretty mild, so the risk is all yours!

Southern Quebec

Southern Quebec refers to Montreal, Quebec City, Sherbrooke and eastern areas of Ontario, such as Ottawa, Cornwall and Kingston. Over here, the forecast looks pretty similar to that in Atlantic Canada, with average temperatures around Halloween being 7 degrees, with a small chance of rainfall. If you’re dressing up in Southern Quebec, you might get away with going snowsuit-free! Woohoo!

Southern Ontario

Off to the other-south, which includes Toronto and the GTA, the weather looks a little bit warmer for the end of October! In fact, there are average temps of 10 degrees for the Halloween month, with similar, slight chances of rain throughout the month.

If you’re planning on dressing as a Mean Girls-style mouse this year, Southern Ontario is where you’ll be warmest!

The Prairies 

For those over in southern Manitoba, Saskatchewan and Alberta, the Almanac has good news for you! Average temperatures will be up to 4 degrees higher than usual, with temperatures sitting at around the 10 degree mark!

Even better, the Almanac describes the weather conditions as “mild and sunny” for the end of October, perfect for Halloween parties!

Southern British Columbia

If you’re over in Southern British Columbia, the news for you isn’t too bad either! There will be average temperatures of around 10 degrees towards the end of the month, with a chance of showers, and conditions that feel ‘warmer than normal.’


Sadly, things aren’t looking so good for those in the Yukon region, who are expected to have temperatures of just 5 degrees around Halloween. However, don’t be too disappointed, as this will still be warmer than usual for October in the region. Some costumes look better with a snowsuit underneath!

Northwest Territories 

If you’re out in the Northwest Territories, I have extra-bad news for you. The end of October is going to be super-cold, with temperatures of just -6 degrees, ouch! In fact, the Almanac predicts above-normal precipitation, and above-average snowfall, with the snowiest period being, yep-you guessed it, in late October.

Maybe just watch a scary movie, instead?

Hopefully this will give you some indication of how to properly prepare for Halloween in your area, and give you an idea of what kind of outfit you should be wearing!
