Keep in mind that the meteorological standard is that wind direction indicates the direction the wind is blowing from and not the direction the wind is blowing toward. So, a reading of "W" or 270° means the wind is blowing from the West. Both you and the device should face directly into the wind.
Considering this, what direction is an easterly wind?
Wind direction is usually reported in cardinal directions or in azimuth degrees. Wind direction is measured in degrees clockwise from due north and so a wind coming from the north has a wind direction of 0 degrees; one from the east is 90 degrees; one from the south has a wind direction of 180 degrees.
What does it mean when the wind is NNE?
Meteorologists always define the wind direction as the direction the wind is coming from. That's why north winds generally bring colder weather to Chicago, while south winds imply a warmup. For general purposes, the wind direction is reported to eight compass points, (i.e. N, NE, E).
What does it mean when it says winds NW?
These instruments point into the wind so they would point north during a north wind. Likewise, winds don't have to come directly from the north, south, east, or west. The winds can also come from the northwest or southwest, which means that they blow toward the southeast and northeast respectively.
