Istanbul straddles the Bosphorus where Black-Sea air keeps summer highs humid and capped; the new airport (LTFM) sits on the northern coast. Settles on the LTFM METAR (NOAA); we track the Turkish Met Service's airport station (0.1 °C, sub-hourly) ahead of it. polyweather.today tracks minute-by-minute runway temperatures from Istanbul Airport (LTFM) (LTFM) — the same sensors behind the official METAR — and turns the trend into a next-METAR nowcast, so you can read where Istanbul'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). Istanbul Airport (LTFM) issues a new LTFM METAR roughly every 30–60 minutes, and daily-high temperature markets settle on those reports. The latest raw LTFM 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.
