Hello, I thought I'd share this with you.
I run a website which since 7. April compares historical temperature
averages with the current monthly average.

I have been observing for a number of days now the above normal temperatures
in London, which are over 7 degrees Celsius for the month of April, on
http://satellite.ehabich.info/eucrescent.htm or
http://satellite.ehabich.info/eu.htm

The deviation of +7 Celsius is a temperature record for Europe and I have
checked now a few times if there are errors in my formula and calculations.
But this is not so.

Nevertheless, I have changed the weather station so that it is easier (more
accurate) to compare the temperatures from London City Airport,
to London Gatwick Airport.

Gatwick Airport historical temperature data span over a period of over
thirty years, from 1961 to 1991.

The figures which display the average temperature deviation show the
difference between historical temperatures average (sometimes climate
records of over 200 years!) with the current monthy average, which is
calculated as the month progresses!

This first months running average is possibly a bit higher than average,
because I am recording the temperatures from the 7th of April, instead of
the 1st of April.

My sources for calculations are
http://weather.noaa.gov/weather/current/EGKK.html and
http://www.worldclimate.com/cgi-bin/...1202+0005305G2 from
GHCN Beta.

My running average is calculated every 60 minutes.
