What does it mean when the METAR of an airport is written with red letters?
It’s to show visibility I believe. Red means incredibly low.
You can go to EDDF now and see why METARs are written in red there.(very low visibility) You can also see a red dot on the airport.
Check this site for how to read METARs: Metar decoding
This is an easy way to figure it out. There are 8 tutorials I believed I’ll give you the first two links to get you started.
