UK min. temps on Friday night http://tinyurl.com/6nsn75

Benson, Solent MRSC and Manston 16.1°C, Heathrow 16.5°C,
Shoeburyness 16.8°C, Gravesend 16.9°C, London MO 17.0°C.

I can understand why London sites would have such high minima - because
of the heat-island - but why some of these others?

I think that, with the exception of Benson, the other non-London sites
are all coastal. Benson is a surprise to find in that list.
