That the *previous* record for Wales is given as 26.4°C at Ruthin
in
1985 (1st October).

But I have a note, taken from 'official' sources some years ago,
that
the highest October value for Wales was 26.7°C (presumably 80°F
observed, subsequently converted) on October 3rd in 1908. This was
recorded at Betws-Y-Coed (Conwy/Snowdonia) and was part of a
remarkable very warm/hot spell that also gave Scotland its October
record of 25.6°C at Elgin on the 2nd in 1908 ... both these values
are
absent from the Met Office 'extremes' data base via this link

Does anyone know what happened to these values? Were they found
'wanting' with the passage of time, or is this a case of the
database
not 'starting' until a certain point?


Maybe it's been decided, not unreasonably, that it's not really
pukka to
convert a value that was presumably only recorded to the nearest
whole
Fahrenheit degree into a Celsius value incorporating tenths of a
degree.
If you argue that that 80°F value would have been at least 79.5 (or
maybe 79.6) and at most 80.4 (or 80.5), then we get a range from
26.4 to
26.9 for the "true" Celsius value.
