Wind Speed Explained: What the Numbers Mean

Wind speed describes how quickly air moves. Weather services may report a sustained wind speed and separate gust values. A gust is a brief increase in wind speed and can be more disruptive than the average wind.

Units and gusts

Wind may be reported in kilometres per hour (km/h), miles per hour (mph), metres per second (m/s), or knots. Check the unit before comparing forecasts. A forecast showing moderate sustained wind can still include stronger gusts, especially near thunderstorms or exposed coastlines.

Why wind matters

Strong winds can make cycling and driving difficult, move loose outdoor objects, affect boating, and increase the risk of falling branches. Wind can also make cold conditions feel colder by increasing heat loss from exposed skin.

Plan safely

Secure loose items before windy weather, use extra care around trees and temporary structures, and check official warnings before travelling. Conditions can vary sharply between sheltered streets and exposed bridges, hills, or coastlines.
