METAR and TAF Codes

RAJ
! ! ! ! ! ! METAR
Reports are generated once an hour or half- hour, but if conditions change significantly, a report
known as a special (SPECI) may be issued

In addition, a short period forecast called a TREND may be added at the end of the METAR covering
likely changes in weather conditions in the 2 hours following the observation.

The complement to METARs, reporting forecast weather rather than current weather, are TAFs.

Note that there may be minor differences between countries using the international codes as there
are between those using the North American conventions.
The 2 examples which follow illustrate the primary differences between the 2 METAR variations.

! ! ! ! ! ! ! TAF
TAF (Terminal Aerodrome Forecast) is a weather forecast at an airport or military base for a specific
period (usually 24 hours).

AMD (Amended Aerodrome Forecast) is issued because the previous version is no longer
representative of the current or expected weather. The amended TAF supersedes the previous TAF.

COR (Corrected Aerodrome Forecast) is a TAF that has been corrected. When a corrected TAF is
issued, disregard previous TAFs.

DAY/TIME KSTL example, 05 is the day of the month and 1130Z is the UTC time of issuance.
051212 indicates that the forecast is valid from 1200Z on the 5th day of the month to 1200Z on the
6th.

TEMPO represents a temporary condition. In this example, TEMPO 1316 1 1/2SM BR reads,
“Temporary condition between 1300Z and 1600Z of
1 1/2 statute mile visibility in mist.” Only the temporary changing conditions are included in TEMPO
groups.

FM means “from” and indicates a rapid weather change where all data groups in the previous line are
superseded. In this example, FM 1600 reads, “From 1600Z ... ”

BECMG means “becoming” or a “gradual change” in meteorological conditions and becomes the
predominant group by the end time listed.
In this example, BECMG 2224 reads “Becoming from 2200Z to 2400Z.”

PROB40 represents a 40% probability or chance of conditions occurring along with associated
weather conditions (wind, visibility, sky conditions).
In this example, PROB40 0006 2SM TSRA 0VCOO8CB reads, “40% chance between 0000Z and
0600Z of visibility 2 statute miles in moderate thunderstorms, 800 overcast cumulonimbus clouds.”

CAVOK (ceiling and visibility OK). CAVOK is used when there is no significant weather, the visibility
is 10 km or greater, and the ceilings are greater than 5,000 ft.

Forecast visibility in statute miles up to 6 SM, beyond which P6SM is used to indicate forecast
visibility greater than 6 statute miles.

NSW (no significant weather) is used to indicate that the weather or obscuration listed in the previous
group is no longer expected to occur. Absence of a weather or obscuration group means that no
weather or obscuration is expected during the forecast period.
