How to read the TNCM METAR
A METAR always follows the same order, so once you know the pattern you can read any station, including TNCM, at a glance:
- Station & time, the ICAO code (TNCM) and the observation time in UTC (Zulu).
- Wind, direction in degrees true and speed in knots, with gusts after a G. This is what SkyStudy matches against the Princess Juliana International Airport runways above.
- Visibility & weather: prevailing visibility, then any precipitation or obscuration codes.
- Cloud, cover and base in hundreds of feet AGL (FEW, SCT, BKN, OVC).
- Temperature / dewpoint and the altimeter setting close out the report.
This is the same operational weather language tested across EASA ATPL Meteorology and Flight Planning. Prefer a guided walkthrough? Use the full METAR & TAF decoder.
