My mum is fed up, she likes the summer but, is too hot, I have told her I will ask you nice people where she can live with a constant summer temperature of around 25oC and a moderate winter :-)
Anywhere in the southeast United States, Virginia on down to Florida. Also California, but only south of San Francisco. Did you mean a place in Britain, or a place in Europe, or an English-speaking location, or anyplace in the world? We will try to help you!!!
