My sister and her family left (for a week in Egypt staying with friends) on Sunday night.
On Monday the temperature was about 21-22C: pleasantly warm, if a little cloudy. I didn't put a sweasthirt or fleece on when I got up, and wondered if the time had come to abandon them. In the morning, I did a quick clean of the guest flat (although they'd left it very tidy and clean) and made up a bed, as a work contact of Richard's was staying overnight.
By lunch-time, I was feeling distinctly chilly so I found a sweatshirt. By evening I was even colder, so I put a fleece on too. Then had an email from Richard's mother (who's coming to stay for a week, arriving this evening) saying that it had been 26C in the South of England...
Yesterday, the morning dawned clear and sunny, but not particularly warm. Showers were forecast, so when I went out to help at the Mothers-and-Toddlers group, I wore jeans and a sweatshirt, and had an umbrella with me. I had to use it on the way back. Perhaps due to the clouds it wasn't particularly cold, however.
Today, once again, the sun was shining when I got up. The forecast was for sunshine all day. I tidied up the plants on our front porch, and did some more cleaning in the guest flat. I even cleaned the windows, which was perhaps a mistake: around noon the sky suddenly turned grey, and about half an hour later there were spots of rain, followed by a torrential downpour and thunder.
The weather site is showing the temperature as 16C. I can believe it. I just hope it doesn't rain all week!
