I was only 4 & half that summer, but have a number of memories. One thing that did strike me was how people coped in cars without aircon.
That was the summer that I spent, from the Whit halfterm onwards, weekend commuting between Manchester and Kent, having not managed to synchronise change of job with sale of house. I assure you that whatever memories you may have of Lancashire at that time, the conditions were basically pretty normal compared to what Kent was experiencing.
The then new rolling stock on British Rail was air-conditioned which was fine until it broke down, as happened on one occasion, and there were no windows that could be opened for a breeze.
