Thanks for the heads up.
I started and have ended the day in Gravesend where I live but I was at work through the day mostly around Surrey and Heathrow( twice) earlier and a little drive to the chilterns which was lovely windows down, all the pollen blowing around was a bit of a irritant) but its better than my usual drive into the big smoke of central London that I will be back doing tomorrow. It's funny how it's always the same 3 or 4 locations that record the highest temperatures depending on the wind direction.
