St Swithun's Day results (40 days on): Hasn't the weather been awfully wet this summer? Well, yes and no, and I have the data to prove it. I've been checking the weather every day since Wednesday July 15th to see if at least one raindrop fell on London, or not. It chucked it down back on St Swithun's Day, so the superstitious amongst you might have expected 40 days of rain, but that's not quite the way it turned out...
My data shows that exactly half of the last 40 days have seen rain, and exactly half have stayed dry. That's more damp days (50%) than the long term average (30%) might predict, but by no means a complete washout. So far August has been noticeably drier than July, which is great news if you've been off work recently. Rain has also tended to avoid Saturdays and Sundays, on the whole, whereas every single Thursday since mid-July has been wet. Don't go blaming a dead archbishop for this, and don't blame global warming either. Our weather is merely very good at being random, and next summer's pattern will almost certainly be completely different. In the meantime it's fingers crossed for the bank holiday weekend (and best pack both suncream and a brolly just in case).
