Wind is moving air, and we can measure its speed and direction. Wind speed is how fast the air is moving, usually measured in miles per hour (mph) or kilometers per hour (km/h). Wind direction tells us where the wind is coming from, like north, south, east, or west. Anemometers and wind vanes are tools that help us measure these aspects of the wind. Understanding wind is important for weather forecasting and many other things!
