Thanks for that link - that a great site. I have just ordered a weather station so will add mine to that when it comes - been champing at the bit waiting for it to come - emailed the company and theyre are on a shut down until 4th Jan dohhhhh!!!
Just checked the weather station nearest to me in Derby and it has a dewpoint of -7 - what does that mean seems a bit low
