@gingercat02 it is indeed lucky you did!
@socks1107 Re variations by region, I'm used to checking by postcode and it was ever so good in the recent past. A previous boss used to cycle to work and would decide if a late or early departure might make for a nicer ride.

The strangely hot half hour was just that! It quickly became cold again.
I'm just going to assume cold and if they forecast a heatwave, that might mean we get 20c!
