I hate hot and dry weather so this summer is a contender for the worst summer since I moved to the UK, but of course it is still early days.
Other than this one, 2003 and 2006 although at least they had some thunderstorms (especially 2003).
Before 1997 i was in Greece so pretty much every summer was horrible with 1995 the bright exception. That summer the maximum temperature in northern Greece was in the 28-32c range and there were afternoon thunderstorms almost daily. That was the best summer of my life actually. By the way, 28-32c is quite low for Greek standards.
