The speed at which air moves in the atmosphere, measured in units such as kilometers per hour (km/h) or meters per second (m/s).
example
Der Wetterbericht meldet für morgen eine Windgeschwindigkeit von bis zu 80 km/h.
The weather report forecasts wind speeds of up to 80 km/h for tomorrow.
Usage tips
Word composition
The word is a compound of 'der Wind' (wind) and 'die Geschwindigkeit' (speed). The 's' in the middle is a linking s that connects the two words.
EXAMPLE
Die hohe Windgeschwindigkeit machte das Segeln gefährlich.
The high wind speed made sailing dangerous.
Typical verbs
Common verbs used with 'Windgeschwindigkeit' (wind speed) are 'messen' (to measure), 'erreichen' (to reach), 'zunehmen' (to increase), or 'abnehmen' (to decrease).
EXAMPLE
Meteorologen messen die Windgeschwindigkeit mit einem Anemometer.
Meteorologists measure wind speed with an anemometer.
Stating the speed
To state the value, people often use the preposition 'von' (of) or the verb 'betragen' (to amount to / to be). The phrase 'eine Geschwindigkeit von X haben' (to have a speed of X) is also common.
EXAMPLE
Der Sturm hatte eine Windgeschwindigkeit von über 120 km/h.
The storm had a wind speed of over 120 km/h.
Register and context
This word belongs more to technical and written language. You find it mainly in weather reports, in seafaring, aviation, or scientific texts.
EXAMPLE
Für den Betrieb von Windkraftanlagen ist die Windgeschwindigkeit ein entscheidender Faktor.
Wind speed is a decisive factor for the operation of wind turbines.

Windgeschwindigkeit vs Windrichtung
wind direction
'Windrichtung' and 'Windgeschwindigkeit' both belong to weather vocabulary and describe the wind. But they do not mean the same thing. 'Windrichtung' tells you which compass direction the wind comes from, for example from the west or northeast. 'Windgeschwindigkeit' tells you how fast or strong the wind is blowing, for example 40 kilometers per hour. The words can be confused because both are often mentioned together in weather reports. The practical question helps: 'Where is the wind coming from?' is the 'Windrichtung'. 'How fast is the wind blowing?' is the 'Windgeschwindigkeit'.
Windgeschwindigkeit
Am Bahnhof zeigte die Anzeige eine Windgeschwindigkeit von 70 Kilometern pro Stunde.
At the station, the display showed a wind speed of 70 kilometers per hour.
Windrichtung
Für die Segeltour prüfen wir zuerst die Windrichtung.
For the sailing trip, we first check the wind direction.
