Decoding METAR reports

Like TAF reports, reading a METAR is not very difficult: they both use the same format. It takes some time to get used to reading these abbreviations but this learning process will happen very quickly. Below we have a table with examples of METAR reports.

Apart from our example below, see the next link to obtain actual current TAFs or METARs from airports around the globe. For a more detailed explanation see this METAR/TAF manual. Note: end of 2008 (Nov, 5) some changes were made to the TAF format.

SKC=sky clear (0=ctas), FEW=few (1-2octas) SCT=scattered (3-4octas), BKN=broken (5-7octas) OVC=overcast. Only two types reported, TCU and CB
CAVOK CAVOK 'cav-oh-kay'
clouds and visibility ok
Visibility greater than 10 km, no CB, no cloud below 5000' and no significant weather
Temp / Dew point 10/03 'Temp 10 degrees and 03 degrees' If no dew point then it shows 10///
QNH Q1042 'QNH 1042' Q indicates millibars (hecto pascals), A means inches of mercury

BECMG=becoming, TEMPO=temporarily, NOSIG=no significant change, NSW=no sig weather, AT=at, FM=from, TL until, NSC=no sig cloud

To complete this we have included a fictional METAR from Amsterdam/Schiphol airport:
