  • SURFACE WIND

  • Wind direction in reference to TRUE north and is reported to the nearest 10°.

  • Wind speed is a 2 minute average reported to the nearest knot .

  • Calm wind is shown as 00000KT.

  • VRB is used when direction is variable and speed is less than or equal to 6 knots. Example: VRB05KT
