In METAR wind data, the direction is referenced to which north?

Explanation:
Wind direction in METAR is given as the direction from which the wind blows, referenced to true north. Using true north provides a fixed, universal reference for weather data worldwide, because magnetic north shifts over time and varies by location. If magnetic north were used, wind directions would differ depending on where and when the observation is made, making reports inconsistent across airports. Therefore the standard is to reference true north, not magnetic north or a magnetic bearing. For example, a wind from the north is reported as 360°, from the east as 090°, and so on.
