Helsinki (EFHK) live METAR, runway temperature & next-METAR nowcast

Helsinki's high-latitude summer keeps the daily high moderate; we track FMI's on-airport 10-minute observations, ahead of the half-hourly METAR. polyweather.today tracks minute-by-minute runway temperatures from Helsinki-Vantaa Airport (EFHK) (EFHK) — the same sensors behind the official METAR — and turns the trend into a next-METAR nowcast, so you can read where Helsinki's temperature is heading before the next METAR prints.

EFHK METAR — the official report behind this page

A METAR is the airport's official routine weather observation (the TAF is the matching forecast). Helsinki-Vantaa Airport (EFHK) issues a new EFHK METAR roughly every 30–60 minutes, and daily-high temperature markets settle on those reports. The latest raw EFHK 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.

What this page shows
