I'd like to add a vote for 2002. The only thing remotely interesting I remember about that year was a warm, thundery spell which occurred when the Commonwealth Games were going on in Manchester. 2011 is saved thanks to that exceptional late autumn heatwave, otherwise it was a waste of warm synoptics (I think that April has been overrated, though obviously fascinating from a purely meteorological perspective). Of course even the second warmest year since 1659 couldn't stop all three summer months being below the 1659-present day average. A frustrating year. 2012 was at least interesting in its appallingness.
