Running in Seattle in July: FAQ
Is it good to run in Seattle in July?
Generally yes, with sensible timing. The typical daytime Run Score is 76 (Good), with temperatures around 67°F (19°C) and comfortable dew points. The best window is usually 6–9 AM.
How hot is it for running in Seattle in July?
Typical temperatures average 67°F (19°C) (Warm) with dew points near 54°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.
