Running in Montreal in August: FAQ

Is it good to run in Montreal in August?

Generally yes, with sensible timing. The typical daytime Run Score is 77 (Good), with temperatures around 66°F (19°C) and pleasant dew points. The best window is usually 6–9 AM.

How hot is it for running in Montreal in August?

Typical temperatures average 66°F (19°C) (Warm) with dew points near 58°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.
