Toronto winters are basically a personality test. You’ve got the people who embrace the slush with $1,000 parkas and the ones who just... complain until May. Honestly, though, if you're looking at the Toronto weather 10 day forecast right now, you're probably just trying to figure out if you need to shovel the driveway again or if the salt is going to do the heavy lifting for you.
We just came off a massive wallop. Yesterday, Friday, January 16, parts of the GTA were absolutely hammered. Scarborough North saw over 50 cm of snow. It was the kind of storm that shut down universities and turned the 401 into a parking lot. But if you think the city is done with the white stuff just because the "Major Snowstorm Condition" was declared, you’re in for a reality check. Winter 2026 is leaning into its "traditional" roots, and the next week and a half is looking like a rollercoaster of temperatures and persistent flurries.
The Biting Truth of the Toronto Weather 10 Day Forecast
Here is the thing about January in Toronto: it’s rarely just one thing. Today, Saturday, January 17, we are sitting at a current temperature of 34°F. That sounds manageable, right? Wrong. The wind is coming in from the southwest at 13 mph, making it feel more like 25°F. We’ve got a mix of rain and snow falling, which is basically the worst-case scenario for your boots.
Tonight, the temperature is going to plummet to 17°F. That means all that slush from today is going to freeze solid by Sunday morning. If you're heading out to Nathan Phillips Square for some skating or hitting the Toronto International Boat Show at the Enercare Centre, you’ve gotta layer up. Sunday’s high is only 22°F, and by Sunday night, we're looking at a low of 16°F with more snow showers.
Why the Polar Vortex is Playing Games
You might have heard meteorologists like Doug Gillham from The Weather Network talking about the polar vortex. Basically, it’s a big swirl of cold air that usually stays up north. But this year, it’s weak. When it breaks, that Arctic air spills down into Southern Ontario like a freezer door left open.

This is exactly what’s happening as we move into next week. Check out this dip:
- Monday: 23°F high, but dropping to 12°F at night.
- Tuesday: A high of only 14°F. That is a bone-chilling Tuesday.
- Wednesday: A brief "warm-up" to 32°F, but it comes with a 25% chance of snow.
The wind is the real killer here. We’re expecting gusts from the west reaching 22 mph on Monday. In a city of glass towers, those wind tunnels make a 14°F day feel like a trip to the moon.
Is La Niña Actually Helping Us?
Sorta. We are currently in a weak La Niña phase, which usually means more variability for us here in the Great Lakes region. Environment and Climate Change Canada noted that this is our fifth La Niña in six years. While it often brings "colder than normal" tags to the forecast, it also means the storm tracks are incredibly unpredictable.
One day it’s a "Texas Low" bringing rain; the next, it’s an "Alberta Clipper" bringing a quick 5 cm of powder. For the back half of this 10-day stretch, the volatility is real. Friday, January 23, looks to be around 26°F, but then Saturday, January 24, we hit a literal wall. We are looking at a high of -1°F and a low of -9°F.
Yes, you read that right. Sub-zero highs.
That is the "fierce frost" the Farmer’s Almanac warned us about for the end of January. When the temperature stays that low, salt stops working. Most road salt is basically useless once you hit -10°C (14°F), so Saturday and Sunday (Jan 24-25) are going to be exceptionally slick.

Dealing with the "Grey" of January
It’s not just the cold; it’s the lack of sun. Historically, Toronto only gets about 8.5 hours of clear or sunny skies a day in January. Most of the next 10 days will be overcast or "mostly cloudy." It’s a mood. If you’re feeling that seasonal slump, you aren't alone. The humidity is hovering around 80%, which makes the cold feel "wet" and "heavy." It gets into your bones.
Practical Steps for the Next 10 Days
Don't just stare at the thermometer and sigh. There are things to do to survive this stretch.
1. Winterize your vehicle immediately. If you haven't checked your tire pressure since the temperature dropped, do it now. Cold air makes the pressure drop, and with the icy Saturday (Jan 24) coming up, you need that traction. Keep an emergency kit in the trunk—blankets, a shovel, and some extra windshield washer fluid.
2. Manage your home's humidity.
The air outside is actually quite dry once it freezes, but we keep our houses sealed tight. This leads to condensation on windows which can cause mold. Use a dehumidifier if you see moisture pooling on the glass, but keep a moisturizer handy for your skin. The "invigorating" air quality is a nice way of saying "it will crack your knuckles."
3. Layer like a pro. Don't just wear one giant coat. You want a thermal base layer (merino wool is the GOAT), a middle insulating layer, and a windproof outer shell. Since we’re expecting winds from the northwest at 15-25 km/h throughout the week, that outer shell is non-negotiable.
4. Plan for the "Deep Freeze" Weekend.
Saturday, Jan 24 and Sunday, Jan 25 are going to be the coldest days of the month so far. If you need to do grocery runs or outdoor chores, get them done by Thursday, Jan 22 when it’s a relatively "balmy" 19°F. Once we hit that -9°F low on Saturday night, you’ll want to stay inside with a movie and some takeout.
The Toronto weather 10 day forecast is a reminder that we live in a city that demands respect for the elements. We’ve got more snow showers coming on Monday, Tuesday, Wednesday, and Friday. It’s a marathon, not a sprint. Keep your shovel by the door and your boots by the vent.

Keep an eye on the wind direction specifically. When it shifts to the northwest, as it's expected to on Saturday the 24th, that’s when the lake-effect clouds really start to dump. Even if the "official" forecast says a 15% chance of snow, a shift in the wind can bring a sudden squall that blinds you on the Gardiner. Stay weather-aware, Toronto.
