I love a hot summer, Last week we were regularly getting into the 30+ range, and re: the classic hot bedrooms, I invested in a couple of tower fans which at least circulate the air in the bedrooms. and have made a homemade 'netting on a frame 'bug screen' which means my wife and I can leave the window open and allow cooler air in without being bitten to death.
However i have been working close to Heathrow the last couple of weeks (that great concrete retainer of heat), and staying in a hotel with air conditioning, the real answer to the hot night problem . I'm also working in the day in an air conditioned office and driving to he hotel in an air conditioned car , so i'm actally only experiencing the current hot weather at weekends and during a 30 minute lunch break!
