Do you have long-term averages you can put alongside those please Stephen?

Sounds like it might almost have been sufficiently recordbreaking that you could have added a:

Minimum rainfall in 1 day

figure

Ill have to dig up some stats later on for that.

Amazing stats from all for Summer 2012, especially Stephen,

The 14th August sticks in my mind since I was tracking the storms around this area that day !
Also, considering the quote below, I'm perhaps 17 miles inland from Stephen, but I could see storms over Liverpool / Wirral !
From the temperature perspective, it's usually much milder here too with a westerly

The nearest LTA station now is Heathrow, 60 miles inland, and is not representative of the weather here.

Anyway enjoy the current 'sunny' weather, albeit a little fresh in the breeze 'up north'

Dave I was looking into when the Gravesend Broadness station opened (It was December 31st 1995) when I came across this link: http://tallbloke.wordpress.com/2012/08/ ... e-station/ Makes an interesting read...

How spooky I was looking into when they moved Gravesend Weather station from the PLA building in Gravesend, to Gravesend Broadness today, and came across THIS There is a lot of discussion, but with local knowledge I felt compelled to reply.

What came back was
