It was hot and dry. I was 14, lived in London and I remember getting horrendous Chickenpox that summer, so that dealt with a fortnight off school (although Mum got my work sent home) and spending a considerable amount of time sitting in a cool bath, to deal with the heat and spots, forget the medical wisdom of that, you do what works! The sun helped with the healing, plus we had so many swimming pools, lidos to use, that's where we spent free time and no sessions for groups, you wanted a swim, then off you went, for as long as you wanted. Doors and windows open, never worried about being burgled, knew our neighbours really well, people sat outside chatting at night, kids ran around half naked with makeshift paddling pools set up... Victorian school building, marble floors, so dealt well with the heat, offices, well Dad worked outside, so changed his hours, Mum in old style low offices, again, windows, construction that seemed to be less sweaty box than some I encountered in my working life (I used to visit Mum at work). We didn't carry water bottles, but had drinking water taps at school and even the parks had drinking fountains, which we happily used!! We just got on with it, no choice, but there were definitely less people in London, parks were our regular picnic spots and everybody used them happily. Attitudes were very different too imo, a very different approach than today, more pragmatic. It was hot, we made the most of it.
