I am a past "Essex Summer School in Social Data Analysis and Collection" student (years 2001, 2002 and 2003) and after discovering your nice and interesting website I often take a look of it. As a small suggestion, I would propose to show yearly NOAA of current and previous years (...I wasn't able to find them).
I saw that in last july your monthly mean temperature was very similar to the coldes july ever in history (say, last 120 years) in my town, that is in slope in a valley between dolomite mountains and Adriatic Sea (coord. 46.10N,12.24E)! I remember that during the 2003 Summer School in july the heating often started!
May I ask a question? I have been told that apart from the different continentality, the yearly mean temperatures in Southern England are not so much different from those in Northern Italy. Which was your yearly mean in 2009 (integration method)? Mine was 10.5°C at 520 meters asl elevation. I also got 1799 mm of rain in 137 days of rain, figures that look like quite "british". :)
