We expect temperatures as you wake up early Saturday morning to range from -35°C to -40°C in this area with the wind chill making it feel close to or below -40°C. Those closer to Lake Superior and Georgian Bay will be slightly warmer with the minimum temperature between -30°C and -35°C. The rest of Northern Ontario should see temperatures in the -20s but won’t be cold enough to warrant us including it on the map. Temperatures will quickly warm up tomorrow during the day as the cold Arctic air pushes out to the east.

Extremely Cold Temperatures Return to Southern Ontario Tonight Into Saturday With a Wind Chill Between -30°C and -40°C

/

It should be no surprise to see colder temperatures across the region this time of year considering that we're in the middle of January. However, we’re expecting some of the coldest air of the season so far to make its way into Southern Ontario just in time for the weekend. Now the actual air temperature likely won’t be as cold as we saw earlier in the week, but the difference will be the slightly stronger winds which will make it feel significantly colder than what the thermometer shows.

In some cases, the wind chill will be 5-10°C colder than the air temperature meaning even areas as far south as the GTA could experience wind chills near -30°C on Saturday morning. Further north, it will feel close to -40°C especially over Northeastern Ontario and through the northern parts of Central Ontario.

For the actual temperature, we expect it to range from -30°C to -35°C for those in Northern Muskoka, Algonquin Park, Bancroft and up into Northeastern Ontario. The rest of Central Ontario, around Lake Simcoe and into Eastern Ontario will be slightly warmer with a low temperature of -25°C to -30°C. For the K/W area into Northern GTA away from the lakeshore, the temperature will end up around -20°C to -25°C and closer to -15°C and -20°C for the Lake Ontario and Huron shoreline. The warmest temperatures will be found in Deep Southwestern Ontario and the Niagara region ending up close to -15°C.

These temperatures are the minimum temperatures that will be felt mainly early in the morning and will warm up later in the day. But there won’t be that much of a warmup with most areas seeing a daytime high between -10°C and -20°C. Those in Central Ontario may even struggle to warm up above -20°C. Remember these are the raw air temperature - you have to add 5 to 10°C to the temperature to get the wind chill. We’ve provided a rough estimation of the wind chill on our forecast map above. Another very chilly night is expected on Saturday and continuing into Sunday although the wind chill doesn’t appear to be as big of a factor compared to tonight. More details on that to come on Saturday.

Please be sure to dress accordingly if you’re planning on being outside for an extended period of time. Frostbite and other cold-related dangers can become life-threatening in a matter of minutes with temperatures this cold! And please don’t forget about your furry friends. If it’s too cold for you, it’s too cold for them! Bring them inside or find a way to keep them warm. Stay safe and warm!

The extreme cold makes a return to Northern Ontario overnight and Friday morning with temperatures well below -30°C throughout the region. This will likely be the coldest air of the season so far with the extreme cold encompassing all of Northern Ontario instead of just the far northern part of the province. The wind chill could reach into the mid -40s especially around Hudson Bay and between -35°C and -40°C for areas in the south around Lake Superior and Georgian Bay. The actual air temperature won’t be that much different ranging from -30°C to -35°C in the south and near -40°C for those further north.

Of course, the coldest temperatures will be found early Friday morning and warming up later in the day, but not by much with most areas not even reaching a daytime high above -20°C. Another cold night is expected Friday lasting into Saturday morning. This will be covered in a separate outlook for Saturday.

Please be sure to dress accordingly if you’re planning on being outside for an extended period of time. Frostbite and other cold-related dangers can become life-threatening in a matter of minutes with temperatures this cold! And please don’t forget about your furry friends. If it’s too cold for you, it’s too cold for them! Bring them inside or find a way to keep them warm. Stay safe and warm!

Extremely cold temperatures are expected during the morning hours on Saturday throughout Central and Northeastern Ontario. The air temperature in many locations will reach -25°C or below with the wind chill making it feel below -30°C. The coldest temperatures are expected through the higher elevations of Algonquin Park, Bancroft and Haliburton. Temperatures will moderate later in the day with many areas expected to warm up to a negative single-digit daytime high so the extreme cold will be very brief. Be sure to dress according to the temperature and limit outdoor activity. Cold-related dangers such as frostbite can take only a few minutes to occur with temperatures this cold.
