Planning a Christmas trip to Toronto? Here’s what the weather is usually like in December.
Typical December weather
| Measure | Typical December |
|---|---|
| Average daytime high | Around 1–2°C |
| Average overnight low | Around −4 to −6°C |
| Snow | Several snowy days a month; amounts vary a lot year to year |
| Daylight | About 9 hours; sunset around 4:45 p.m. |
These are long-term averages. Toronto weather swings: one week can bring mild rain, the next a cold snap with wind chills near −20°C.
Will there be a white Christmas?
Maybe. Toronto has a white Christmas (snow on the ground on December 25) in some years and not in others. Lake Ontario moderates temperatures, so the city often gets less snow than areas to the north.
Wind chill
The wind off the lake makes it feel much colder, especially downtown and on the waterfront. Check the “feels like” temperature before outdoor events like the Santa Claus Parade or New Year’s Eve.
Weather through the holiday season
Early December is often cool and damp, with temperatures hovering around freezing and a mix of rain and light snow. It’s a comfortable time for markets and lights if you dress in layers.
Mid-December usually brings colder air and a better chance of snow sticking to the ground. Clear, cold nights are perfect for skating and light displays.
Christmas week can swing between mild, grey days and the first real cold snap of winter. A white Christmas is possible but never guaranteed.
Late December into January is when Toronto’s deeper cold typically arrives, with more days below freezing and occasional bigger snowstorms.
Snowstorms and travel
When a big storm hits, roads, sidewalks and flights can be affected:
- Check Environment Canada’s forecast and weather alerts before outdoor events.
- Allow extra time on the TTC and GO Transit; streetcars and buses slow down in heavy snow.
- Watch for event updates: some outdoor rinks and markets close in freezing rain or high winds.
- Flying? Check your flight status before heading to Pearson. Pearson at Christmas
