Well, I had my swim and it was lovely. I was in the water by 5.30am, a few minutes after sunrise but I couldn't see the sun because it was behind the houses to the north. By 6am, the beach was getting crowded, including a sizeable group who looked as though they had arrived for the day, complete with folding chairs.
When I got up the temperature was 20.6°C. It's now 28°C at 7.25am. Yesterday, it was 25°C at 8.23am, and the maximum was 35.9°C. This does not augur well for the rest of the day. Thunderstorms are forecast for around midnight tonight, followed by a fairly sharp drop in temperature. I do hope they materialise. So far this month, we have had no measurable rain.
