Miami (KMIA) live METAR, runway temperature & next-METAR nowcast

Miami's tropical summer is hot and humid with afternoon sea-breeze storms that cap the peak; we track the 5-minute ASOS, ahead of the hourly METAR. polyweather.today tracks minute-by-minute runway temperatures from Miami Int'l (KMIA) (KMIA) — the same sensors behind the official METAR — and turns the trend into a next-METAR nowcast, so you can read where Miami's temperature is heading before the next METAR prints.

KMIA METAR — the official report behind this page

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