How to read the KSEA METAR
A METAR always follows the same order, so once you know the pattern you can read any station — including KSEA — at a glance:
- Station & time — the ICAO code (KSEA) 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 Seattle–Tacoma 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.

Where does the KSEA 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 Seattle–Tacoma International Airport have?
Seattle–Tacoma International Airport has 3 published runways (16C/34C, 16L/34R, 16R/34L). SkyStudy combines these runway headings with the live KSEA wind to show which runway end is best aligned right now.
Is the KSEA METAR and TAF decoder free?
Yes. SkyStudy publishes this KSEA 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.
