UNDERSTANDING METARS
Refer to the numbers on the following diagram to find the appropriate
descriptions.
1. Type of Report: METAR (SPECI will be seen here if this is a
Special Weather Report)
2. ICAO Station Identifier: KPIT
This is the location for which the METAR pertains.
3. Date and Time of Issue: 201955Z
The 20th day of the month at 1955Zulu or UTC.
4. AUTO indicates the reporting station is an automated station. If the
reporting station is a manned station this element will be omitted.
Also, if a report from an automated station is modified by a person
this element will be omitted. “COR” indicates a corrected report.
5. Wind: 22015G25KT
220 is the 3 digit true direction to the nearest 10°. Airport advisory
service, ATIS and ATC towers report wind direction as magnetic.
“VRB” in this place indicates variable winds less than or equal to 6
knots. If wind direction is varying more than 60° with speeds over 6
knots, an entry similar to “180V260” will be displayed in this place.
This example actually shows wind direction varying by 80°.
15 is the 2 or 3 digit wind speed (in knots).
25 is the 2 or 3 digit wind gust speed in knots (KT) because it follows a
G (Gust).
