CAT III airports
182 airports · by country
Every airport in the atlas whose best ILS category on record is CAT III. The fog hours column is why the category exists: it shows how much of the year each airport would otherwise spend below CAT I minima.
September is off season — these airports together average about 844 hours below CAT I minima in September, against 4,564 in December, the peak month.

Hours/yr = time below CAT I approach minima (visibility under ~½ mile or ceiling under 200 ft), ten-year average of hourly observations. "Forecast" shows whether the airport's calibrated Fog Atlas percentage has passed live verification; every other airport carries official guidance and climatology only.
What does CAT III mean?
ILS categories set how low an approach may continue: CAT I to a 200 ft decision height, CAT II to 100 ft, CAT III to 50 ft or lower with autoland. A CAT III airport keeps landing in fog that closes a CAT I field.
How was this list built?
US airports from the FAA NASR ILS database; foreign airports from the FAA OpSpec C060 list of facilities approved for US-carrier CAT II/III operations, supplemented by national AIP research with a confidence tag on each airport page. An airport can have CAT II/III capability not used by US carriers and be missing here.
