what degree would indicate a soutwest wind?

Answer 1

225, as several answerers have pointed out. On the chance you are looking for more than just a number, let's look at where that number came from; so you can answer your own questions about wind direction.

Traditionally, wind directions are given in the direction FROM where the wind is blowing. So when there is a "north eastern," for example, that wind is coming from the north east. Since north is from zero degrees and east is from 090 degrees, a north easterly wind would be coming from half-way between 000 and 090; that is, from 045 degrees.

Sometimes we hear something like "north north east" as where the wind is coming from. In which case solve the last two words (north east), which we found earlier to be 045. Next solve the first word (north), which means bring the direction half-way up between north and north east. Half way between 000 and 045 is 022.5 degrees, which corresponds to north north east.

As an exercise, just to see if you got it, work out what a wind from south south west is. You've already got south west (225); so move that further south (the first south) half way between 225 and 180...your resulting number in degrees will be south south west.

Answer 2

A north wind is 0 degrees, a south wind is 180 degrees. An east wind is 90 degrees, so a west wind would be 270 degrees. A south west wind is half way between south and west, or half way between 180 and 270, so the southwest wind would be about 225 degrees, if my mental arithmetic is correct.

Answer 3

west is 270 south is 180 so south west would be 180 +((270-180)/2) = 180+45 = 225degrees

Answer 4

On an 8-point compass, that would be 225 +/- 22.5°

On a 16-point compass, that would be 225 +/- 11.25°

Answer 5

235 degrees

Answer 6

Despite my best efforts to decipher your question, I have no idea what you're asking.
