I'm a little perplexed as to why 1989 is considered an underrated summer..rating my top 5 summers of my lifetime before i moved to Canada would look like this:
1. 1995 - Stats wise there is little to choose between 95 & 76 but 95 was different gravy and gets my number 1 by a country mile over anything else
2. 1976 - Although i just about remember 76 i do remember the heat and the endless drought ..what makes it really stand out was the garbage summers that followed.
3. 1983 - Probably the best July of my lifetime extremely sunny and dry ..August was none too shabby either
4. 1989 - Similar to 1983 although more thundery esp. Mid June to Mid July ...heat was more oppressive than 1983 why it comes lower.
5. 1990 - This was a tough one you could easily go for 94, 03 or 06 here but I'm going for 1990 due to what was going on in my life at that time.
