How Is Wind Speed Measured?

Wind speed is the rate at which air is moving past a fixed point, usually reported as a sustained average over a short period along with the peak gust — a brief burst that can be much stronger than the average. Most forecasts express wind speed in miles per hour (mph) in the United States and kilometres per hour (km/h) elsewhere; sailors and aviators often use knots. Whatever the unit, the principle is the same: the bigger the number, the more force the wind exerts on everything it touches.

Two readings matter most when you check a forecast. The sustained wind tells you the general conditions, while the gust tells you the strongest you can expect — and it's usually the gust that snaps branches, flips umbrellas, and makes driving difficult.

The Wind Speed Scale

This simplified version of the Beaufort scale shows what each band of wind speed actually feels like and does:

Wind SpeedDescriptionWhat You'll Notice
0–7 mph (0–11 km/h)Calm to lightSmoke drifts, leaves barely stir. Pleasant.
8–18 mph (12–28 km/h)Gentle to moderateLeaves and small branches move, flags flap, dust lifts.
19–31 mph (29–49 km/h)Fresh to strong breezeSmall trees sway, umbrellas hard to use, whistling wires.
32–46 mph (50–74 km/h)Near gale to galeWalking is difficult, twigs break off, driving affected.
47–63 mph (75–101 km/h)Strong gale to stormBranches down, minor structural damage, hazardous travel.
64+ mph (102+ km/h)Violent storm / hurricane-forceWidespread damage, trees uprooted, roofs at risk.
💡 Gusts are what cause the damage A forecast might show 25 mph sustained winds with gusts to 45 mph (40 km/h sustained, gusting 72 km/h). It's that peak gust — not the average — that brings down branches and makes high-profile vehicles hard to control. Always check the gust figure, not just the steady wind.

What Affects Wind Speed?

Pressure differences: Wind is air flowing from high pressure to low pressure — the bigger the difference over a short distance, the stronger the wind. Terrain: Open plains, coastlines, and hilltops are windier than sheltered valleys, and wind funnels and accelerates between tall buildings and through mountain passes. Time of day: Winds often pick up through the afternoon as the ground heats and calm overnight. Storms: Thunderstorms, fronts, and tropical systems can drive sudden, dramatic spikes in wind speed.

How to Use the Wind Forecast Every Day

Check the wind speed before any plan that the wind can ruin or endanger — cycling, boating, flying drones, working on a ladder, or driving a tall vehicle on an exposed highway. As a rule of thumb, anything above about 25 mph (40 km/h) starts to make outdoor activities awkward, and sustained winds or gusts above 40 mph (64 km/h) are worth treating with real caution. When a forecast pairs strong wind with thunderstorms, expect the conditions to change fast.
