How to read the RJSS METAR
A METAR always follows the same order, so once you know the pattern you can read any station — including RJSS — at a glance:
- Station & time — the ICAO code (RJSS) 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 Sendai 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.
RJSS weather — frequently asked questions
What is the ICAO code for Sendai Airport?
The ICAO code for Sendai Airport in Natori, Japan is RJSS, and its IATA code is SDJ. Pilots use the ICAO code RJSS to request the METAR and TAF for this airport.
How do I read the RJSS METAR?
Read the RJSS METAR in order: station and time, then wind (direction in degrees true and speed in knots), visibility, weather and cloud, temperature and dewpoint, and finally the altimeter setting. The decoder above turns the raw RJSS METAR into this plain-language order automatically.
Where does the RJSS weather data come from?
The live METAR and TAF are pulled from the public NOAA Aviation Weather Center feed, the same authoritative source used in flight planning, and refreshed every few minutes. SkyStudy then layers its runway and wind logic on top.
How many runways does Sendai Airport have?
Sendai Airport has 2 published runways (09/27, 12/30). SkyStudy combines these runway headings with the live RJSS wind to show which runway end is best aligned right now.
Is the RJSS METAR and TAF decoder free?
Yes. SkyStudy publishes this RJSS weather page as a free tool. If you are studying for EASA ATPL exams, the same METAR and TAF language appears in Meteorology, Flight Planning, and Operational Procedures — and SkyStudy turns it into practice questions and mock exams.
