I regularly get the weather right using my Barometer and other instruments in the garden, than the met office do..They do make me laugh, they can't even get the weather correct for the next day let alone the following month..
Well............. I have to say that I've found the weather predictions on the BBC website for my patch to be about 95% accurate on average.
Well, at least we had plenty of practce last winter.
Should be a piece of cake.
