How to identify wind direction based on degrees ?
« on: November 10, 2009, 07:52:47 AM »
Hello,
did any body can write or show me the page that i can get information how to identify wind direction based on compass numerical values ?
I have two pictures, first is compass directions


and second picture is compass direction based on degree



but i can't find exact information at what value of degrees the readings become from N to NNE, NNE to NE, NE to ENE and so on.

N = 0 or 360
NNE = 22.5
NE = 45
ENE = 67.5
E = 90
ESE = 112.5
SE = 135
SSE = 157.5
S = 180
SSW = 202.5
SW = 225
WSW = 247.5
W = 270
WNW = 292.5
NW = 315
NNW = 337.5
N = 360 or 0
The compass (a circle) has 360.  You have 16 points on your compass.  360 divided by 16 equals 22.5 degrees separation between each point.

Keep in mind it would be something like this.

N - 347.5 - 12.5 degrees or +/- 12.5 degrees from 0 degrees
NNE - 12.25 - 34.75 or +/- 12.5 degrees from 22.5 degrees
NE - 34.75 - 57.25 or +/- 12.5 degrees from 45 degrees
etc.
