I noticed that when I export data from weatherlink software (browse->export data), wind direction only appears as N, NE, etc., while I need to see wind direction degrees. Is this possible?

Is this possible?Not when exporting from Weatherlink, though if you're then importing into eg Excel it's presumably not difficult to convert the directions to degrees with a suitable Switch script, which will give you direction to the nearest 22.5°.
unfortunately, I need more precise values, with maximum error of about +- 5°
Thank you all for replying! Yes, taking wind direction from Wunderground is a good idea, and I can actually solve the problem this way. I was just wonderiing why on weatherlink reports wind direction in degrees doesn't appear

I was just wonderiing why on weatherlink reports wind direction in degrees doesn't appear Why do you need maximum error of about +- 5°?The specified accuracy of the Vue is only ±3°And it's really hard to "aim" a Vue to precisely North - without using surveying instruments, etc. How did you aim it (or calibrate the direction)?I'm just curious how you're using the wind direction, that requires a maximum error of about +- 5°
I'm studying sea breeze effect, and in particular the Coriolis' force effect, which should progressively deviate wind direction of about 10-15° (from WSW to W).
