Weather data updated every 10 minutes.
Wind Direction:
This is the direction from which the air is moving. The directions are in terms of degrees from true north (0 degrees), and the angle increases in a clockwise direction. In other words, if the wind direction is 45 degrees, the wind is from the northeast.
Wind Speed:
The wind speed is a measure of the average speed of movement of the wind at a specific point. When measured, the value represents an average taken over a couple of minutes.
Wind Gust:
The wind gust is the maximum wind speed recorded over a specified time period. When wind speeds are measured and the peak wind speed during the measuring period is roughly 10 knots more than the average wind speed, a wind gust is reported.
Wind Chill:
The apparent temperature of exposed skin with a four knot wind that has the same heat loss of exposed skin at a certain certain temperature and wind speed. The higher the wind speed, the higher the heat loss from the skin's surface due to sensible heat transfer. This is calculated from heat transfer algorithms.
