We could go to Rob McElhenney and “It’s always sunny in Philadelphia” and then to the Declan Swans song “It’s always sunny in Wrexham: praising the new co-owner of our local club. But I refer to the weather map pumped out by the BBC and others which always seems to show Wrexham as being that little bit warmer than other parts of Wales and the neighbouring English counties. Is it really always sunny in Wrexham? Er..no.
The nearest weather station to Wrexham where the Met Office gets its readings is at Hawarden. It has a WMO rating of 3. Ratings run from 1 (Pristine) to 5 (totally compromised). A 3 rating means there is a known measurement uncertainty of plus or minus 1%. But in the case of Hawarden the uncertainty is a certainty for the station is at an airport, one used by Airbus for large scale jet cargo flights as well as private flights. So that bumps up the measured temperature next to the runway by an artificial 1 degree.

And that is why, on the weather maps at least, it is always sunny in Wrexham
