Running in Toronto in January: FAQ

Is it good to run in Toronto in January?

It's runnable, but at least one factor — usually heat or dew point — taxes the effort. The typical daytime Run Score is 63 (Mixed), with temperatures around 26°F (-3°C) and comfortable dew points. The best window is usually 6 AM–11 PM.

How hot is it for running in Toronto in January?

Typical temperatures average 26°F (-3°C) (Cold) with dew points near 19°F. Dew point — not the thermometer — usually decides how hard the run feels.

What is a good Run Score?

Scores run 0–100. 97+ is Perfect, 80–96 is Great — conditions are actively working in your favour. 65–79 (Good) is solid. 45–64 (Mixed) means at least one factor — usually heat or dew point — is taxing you. Below 45 (Poor), expect a noticeably harder effort or hold back for safety.

Why does dew point matter more than temperature?

Your body cools by evaporating sweat. When the dew point climbs above roughly 60°F, the air is too saturated for sweat to evaporate efficiently, so heat builds up even if the thermometer looks reasonable. That's why a 70°F muggy morning can feel harder than a dry 80°F afternoon.
