I find most Aramis frags work well in the summer. I'll go Havana or Tuscany.
Don't put your cooler weather frags away, though - we've heard news like this in the UK several times in the last decade, but it's never really come off. Whilst no one went quite as far as "hottest summer ever", last summer was supposed to be exceptionally long, warm and dry. What we actually ended up with was pretty much endless cloud and rain. I don't think I got my shorts out once last year.
So yeah - I'll believe it when I see it. Or feel the heat of it.
