Seattle's marine Pacific-Northwest summers are mild; we track Sea-Tac's 5-minute ASOS, ahead of the hourly METAR. polyweather.today tracks minute-by-minute runway temperatures from Seattle-Tacoma Int'l (KSEA) (KSEA) — the same sensors behind the official METAR — and turns the trend into a next-METAR nowcast, so you can read where Seattle's temperature is heading before the next METAR prints.
A METAR is the airport's official routine weather observation (the TAF is the matching forecast). Seattle-Tacoma Int'l (KSEA) issues a new KSEA METAR roughly every 30–60 minutes, and daily-high temperature markets settle on those reports. The latest raw KSEA METAR is shown at the top of this page, the board lists recent reports with decoded temperatures, and between two reports the minute-level runway feed shows where the next METAR is heading.
