This expression is usually reserved for a warm spell in November, but it has been so gloriously hot and over 20C for the last week that I think it qualifies! The trees are quite brilliant at the moment but are beginning to lose their leaves. Soon it will be time to start raking.
Tomorrow may be the last day, though, as the rest of the week is forecast to be more autumnal - low to mid-teens and some badly needed rain. We had a good game of tennis on Sunday - I actually lasted on the court for the full hour and a half - but didn't do much for the rest of the day. The garden is pretty much tidied for winter but I will keep filling the bird bath until we have minus temperatures. I think the birds are delaying their departure for warmer climes because of the extended summer. Of course, there are still lots who stay around all winter. No idea how they survive!
