5 / 20
In a METAR message, the wind group is 23010MPS. This means:
  • A
    wind from 230° magnetic at 10 miles per hour.
  • B
    wind from 230° true at 20 knots.
  • C
    wind from 230° magnetic at 20 knots.
  • D
    wind from 230° true at 10 miles per hour.

Aviation Routine Weather Report (METAR)

Wind

  • First 3 digits: True Wind direction or average if variable (VRB).

Note: If the wind direction varies 60° or more, the direction will be indicated with a V (e.g. 180V250)

  • Next 2 digits: Mean speed and units

KT=knots, KMH=kilometers/hour, MPS=meters/second

G (gust) as needed – 2 or 3 digit maximum speed; Example: 18012G22KT
Calm will be indicated by 00000KT


=> To convert MPS to KTS, use the value in MPS and multiply by 2. In this case, 10 MPS = 2 x 10 = 20 kts.
     Therefore, we have wind from 230° true at 20 knots.
