Wind direction reported by ATIS,AWOS, METAR and TAF
Is the wind direction reported by ATIS and AWOS/ASOS always reported in degrees from Magnetic North, and is the wind direction reported in METAR and TAF reports always in degrees from TRUE north?
For most of my flying career, I had thought that winds reported for a specific airport or terminal area were reported as magnetic directions, where winds aloft were always reported as true directions.

“If written it’s true. If spoken it’s magnetic.”

METARs, TAFs, and winds aloft are in reference to true north. ATIS, PIREPs, and automated weather reports are in reference to magnetic north.

Something I remember from a college aviation weather course! 😁

Winds shown on a METAR, TAF, winds aloft table, or surface analysis chart are represented in true headings, whereas winds represented through an ATIS, AWOS/ASOS, or PIREP are in magnetic headings. Here is a link to a well written article explaining the logic behind reporting winds as true or magnetic.
