Highest min I've seen is 21.9 at RAF Marham, Norfolk.
Undoubtedly a few local records have gone, and I wonder
about the Scottish one ... 19.5ºC at Aviemore looks very
high for north of the border.

A basic search, incomplete, threw up a couple of 20.0ºC
minima (recorded as 68ºF), so no Scottish record either,
unless a climat. station comes up with something better later
on.
