Cool in the shade ?

In England we NEVER stop talking about the weather.. Really its because we don't have a clue what its doing from one day to the next. 

We've got yellow and amber heat wave warnings, the environment guy on the TV is telling us ways to keep cool - take a cold shower, wash your hands in cold water, hang a wet sheet up at the windows - amazing ?

34 degrees C today and then ...... thats it for a bit. Back to normal.
