Live aviation weather for Seattle–Tacoma International Airport in Seattle, WA, including METAR, TAF, flight category, wind, visibility, ceiling, altimeter, runway crosswinds, and Telegram airport alerts.

Seattle–Tacoma International Airport (KSEA) is one of the primary air-carrier airports serving Seattle, WA at 433 ft. KSEA reports its own METAR and publishes a TAF, and broadcasts digital ATIS (D-ATIS) — decoded live on this page as flight category, wind, visibility, ceiling and altimeter. Its 8 runways (16C, 16L, 16R, 34C) — longest 11,901 ft — are checked against the current wind in the crosswind table below. The official FAA airport diagram is at the bottom of the page. Track KSEA in the ATIS Alerts Telegram bot to get a message the moment the ATIS letter changes or the weather drops below your selected minimums.
