(%)= percentage of twelve year mean.
(+ or -)= difference from twelve year mean.
(...)= since August 2002

TEMPERATURE (0C)
Mean Max: 22.1 (+1.5)

That must be one hell of a micro-climate you've got going up there
if your mean July max is 20.60C and mine is only around 190C!

I haven't done the final July figures for here yet, Col, but the mean daily max
is going to be around 22 deg. Your 19 deg looks to be very low.
