London had a frost last night at Northolt. I'm sure Northolt had a frost a couple of days ago too.
I'm using the stats from Heathrow as it's the closest station to me.
Fair enough, although you probably should've specified Heathrow, as officially, London has already had a couple of frosts. Is Northolt a bit of a frost hollow then?
My nearest weather station at Linton, dropped to -0.1C the other night, so I almost certainly haven't had a frost yet here in York. Shame the only station I can use is 13 miles from where I live, and in the middle of the countryside.

Northolt has similar highs to Heathrow, but the lows are quite a bit lower (same as at Kew).
It's frost hollow but nothing like as strong as at Rickmansworth (which is an artificial frost hollow - it has even lower minima than the sandy soils of Wisley and Farnborough).
Actually, it looks like Northolt's lows are very similar to those of rural Wisley.
First high below 5C: 14 October
First freeze: 21 October
First -5C: 4 November
First ice day: 4 November
First below -10C: 5 November
First trace of snow: 2 November
Bloody premature ejaculation of winter. What's there to wait for anymore?

I'd assume (and I've made this abundantly clear in previous posts) that if he says "London" he is referring to temperature ps taken at the official recording station, which would be Heathrow, not cherry picking the coldest or warmest spots. Following that, I'd say that London has not yet recorded a frost.

Well no, seeing as there's more than one official met office site in London, simply saying "London", implies that he's talking about the whole city. London is a massive city, so inevitably it can have significant temperature differences, particularly away from central London.
As B87 lives near Heathrow, then it makes sense for him to use that site, which is fair enough. As he's now clarified, he meant Heathrow hasn't had a frost, which is correct, however another station (Northolt) has, therefore officially, London has had a frost.
