In METAR, the wind direction is relative to which north?

Explanation:
The wind direction in METAR is measured relative to true north. It indicates the direction from which the wind is blowing, expressed in degrees from 000 to 360, with 090 meaning the wind comes from the east, 180 from the south, and so on. Using true north provides a stable, global reference for weather data and flight planning, because magnetic north moves over time and varies by location. If wind were given relative to magnetic north, readings would shift with declination changes and differ by place, making them unreliable for interpreting weather patterns. Geographic north is essentially the same direction as true north, but METAR conventions use true north as the standard reference, while magnetic north would be inappropriate here.
