Maybe those temperature maps are based on their forecasts, rather than reality . Pretty sure it didn't get above 14c here today, and I'm a long way from the coast .
Been away for a few days. Landed last night in Luton. Drove home to Northants. House was very cold. Had to put heating on. It's not just the East coast where the weather is rubbish.
Supposed to brighten up by 3 this afternoon. I'm not confident of that!
