Running in Boston in July: FAQ
Is it good to run in Boston in July?
It's runnable, but at least one factor (usually heat or dew point) is working against you. The typical daytime Run Score is 63 (Fair), with temperatures around 76°F (24°C) and noticeable dew points. The best window is usually 6–8 AM.
How hot is it for running in Boston in July?
Typical temperatures average 76°F (24°C) (Warm) with dew points near 64°F. Dew point (not the thermometer) usually decides how hard the run feels.
What is a good Run Score?
Scores run 0–100. 80–100 is Great (97+ earns a gold star for near-perfect conditions). 65–79 (Good) is solid. 45–64 (Fair) means at least one factor (usually heat or dew point) is slowing 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.
