Looking at your annual mean temperatures, it shows a very definite rise in
temperature since 1992. Much more distinguishable than my own readings
which are far more 'up & down'.

Due to the high influence of the surrounding sea & ocean at your site, I
would say that this is a very good indicator on how much it has warmed in
our part of the world over the last decade or so.

Quite remarkable really.

Nick,

The warming has been quite remarkable over the last 20 years.

Penzance Average Annual Temperature
1961 - 1990 11.1
1971 - 2000 11.3

7 years 1991 - 1997 11.5
7 years 1998 - 2004 12.1!

Since 1990, the only year with an average annual temperature below the
1961-90 norm was 1996, and that was 11.0 (just 0.1 below the norm)

I think you're right about the effect of the increase in sea temperature.
It's currently still almost 12 degrees off west Cornwall.

Back in the 60's I am sure a NW like the one over Xmas would have given snow
showers here. We've not had snow (to settle) on a NW for 15 years, it has
to be real continental air these days.
