Forgot to say, with an average temperature of 6.3c, this will have
been the mildest Winter since 1988/9 which had an average CET of 6.5c.

For this winter to match that of 1988/9, the average temp for the
whole of February needs to be 5.9c

For this winter to beat that of 1988/9, the average temp for the whole
of February needs to be 6.2c, and this is possible.

The all time record is 6.8c set back in the winter of 1868/9, this
would require an average February temperature of 6.8c to match it, and
an average temperature of 7.1c to beat it. Both of these seem
unlikely with only 1 week to go.
