How to Calculate Wind Chill on a Motorcycle
Bikers understand better than anyone the effect of wind chill. Depending on your speed and the outdoor temperature, it can feel up to 13°C colder to a biker in the winter. In fact, the faster you ride and the colder the temperature, the more you'll feel the impact of wind chill.

No Wind
Riding your motorbike on a quiet day (with no wind) will feel 4°C to 12°C colder, depending on the temperature and your speed. For example, riding at 70 mph on the motorway when it's 0°C will feel like -11°C.
| Wind Chill (no headwind) | 20 mph | 30 mph | 40 mph | 50 mph | 60 mph | 70 mph |
|---|---|---|---|---|---|---|
| 10°C | 6°C | 6°C | 5°C | 4°C | 4°C | 4°C |
| 8°C | 4°C | 3°C | 2°C | 2°C | 1°C | 1°C |
| 5°C | 0°C | -1°C | -2°C | -3°C | -3°C | -4°C |
| 2°C | -4°C | -5°C | -6°C | -7°C | -8°C | -8°C |
| 0°C | -7°C | -8°C | -9°C | -10°C | -11°C | -11°C |
| -2°C | -9°C | -11°C | -12°C | -13°C | -13°C | -14°C |
10mph Headwind
Riding a motorcycle in a 10 mph headwind will make it feel 1-2°C colder than riding in quiet air. For example, the wind chill reaches -8°C when you're riding at 50 mph in 2°C weather versus -7°C when there's no wind.
| Wind Chill (10 mph headwind) | 20 mph | 30 mph | 40 mph | 50 mph | 60 mph | 70 mph |
|---|---|---|---|---|---|---|
| 10°C | 6°C | 5°C | 4°C | 4°C | 4°C | 3°C |
| 8°C | 3°C | 2°C | 2°C | 1°C | 1°C | 0°C |
| 5°C | -1°C | -2°C | -3°C | -3°C | -4°C | -4°C |
| 2°C | -5°C | -6°C | -7°C | -8°C | -8°C | -9°C |
| 0°C | -8°C | -9°C | -10°C | -11°C | -11°C | -12°C |
| -2°C | -11°C | -12°C | -13°C | -13°C | -14°C | -15°C |
20mph Headwind
Riding in a 20 mph headwind exacerbates the effects of wind chill even further. In fact, an 8°C day can feel like 0°C when you're riding your motorbike on the motorway at 70 mph in a 20 mph headwind.
| Wind Chill (20 mph headwind) | 20 mph | 30 mph | 40 mph | 50 mph | 60 mph | 70 mph |
|---|---|---|---|---|---|---|
| 10°C temp | 5°C | 4°C | 4°C | 4°C | 3°C | 3°C |
| 8°C temp | 2°C | 2°C | 1°C | 1°C | 0°C | 0°C |
| 5°C temp | -2°C | -3°C | -3°C | -4°C | -4°C | -5°C |
| 2°C temp | -6°C | -7°C | -8°C | -8°C | -9°C | -9°C |
| 0°C temp | -9°C | -10°C | -11°C | -11°C | -12°C | -12°C |
| -2°C temp | -12°C | -13°C | -13°C | -14°C | -15°C | -15°C |
To counteract the effects of wind chill on a motorcycle, protective gear such as a proper wind-proof jacket and battery-heated gloves can help to keep you warm.
