In Dec 1962 I was working in the Met Office at Heathrow when we had freezing fog for a while with an almost constant -5C night and day - fortunately that was the last real pea souper I recall - shortly after that the Clean Air Act came in and that has made a great difference.

You may be able to find it the records.
