If you could go back through the summer months within your memory and
select individual months (June, July and August) to put together a best
and worst summer ever, what would they be? In other words, what is the
best/worst June, best/worst July, best/worst August you can remember?

For me, the best summer would comprise of something like June & July
2006, and August 2003.

The worst summer would be something like June 2012, July 2007, August 2008.

As you notice, my memory is hazy before 2000 (although I remember the
hot summers in the 90's) and I am relatively young, so I have chosen
recent years.
