Leaving for England in three days: Weather?

At the moment our weather is great , as you say 70 may not be red hot but to us Brits it is like a heatwave and it does not take much for the British to get their shorts on so you will not be out of place. Our weather is so unpredictable though that it could so easily be pouring down with rain by the time you arrive so best if you come prepared for all eventualities .Enjoy your visit.
