This time last week the Festival of Three Cultures was drawing to a close in the August heat. Daytime temperatures were peaking around 30 or 31 degrees and only fell overnight to around 27 or 28. The trick was to switch on the aircon in the bedroom before setting off to the evening concert and closing doors and windows to trap the cool. Then, on returning we would turn off the aircon and switch on the ceiling fan at a low speed for its cooling effect through the night. We began this week in similar vein. Then, around mid-week, something changed. A breeze came in from the west, maximum temperatures only got to 25 or 26 and nighttime temperatures started dropping to the high teens. No aircon, no fan, window open all night. No problems.
So what happened? Well, Wednesday was the last day of August, our notoriously unpleasantly hot month, and Thursday was the first day of September when we know that everything becomes tolerable again. I know that, but how does the climate know? All explanations welcomed!
