Living in a valley we normally get our first frosts in late September.But due to the mild weather none as yet this season.Thought it would be interesting to see what other members experience.

Sometime in October but not every year, in the 17/18 years data I have we did not get an October ground frost in 5 years.

Air frost is less frequent in October with only two years recording them and both had 3, 1997 and 2008.

Seeing as I haven't been taking notice of the weather for more than three years I can only give info going back that far. Last year our first ground frost was in November, in 2011 we had a couple of light ground frosts in mid October and I seem to remember a thick ground frost on I think the 25th October 2010. So I reckon the average is probably around late October/ early November if these dates are anything to go by. Living in the south east they come a bit later than everywhere else.

First visible ground frost and air frost usually occur in October I'd say. We may get a ground frost in September infrequently, but I couldn't say for sure as I haven't been here for that long. On average, we  get air frost in September once every 10 years.

Ground frosts generally occur here in October, or sometimes mid-late September. It only got down to 3c in September though, so we're still waiting.

Air frost is usually late October, or November; very rarely earlier.

Anytime now usually,had a lot of ground frosts in September 1985 and also a sharp air frost,maybe -3 deg which came from nowhere in October in the mid 90s.I remember as I had just done some rendering that day and was shocked as how cold it was the following night,luckily the render was ok

First ground frost here is in September, first air frost almost always by the end of October.

We can have ground frosts in the summer.

So can favoured locations in England, Scotland and Wales.

Around here I'd say that on average our first ground frost is in late October and first air frost early to mid November.  This year we came close to a ground frost in September, which is very rare but not unheard of.

We are in a frost hollow here so tend to get frosts early and late. Around early October would be average for the first frost. Temperature last night fell to just under 4C.

Really depends, most likely October but it has happened on a couple of occasions in September, I've got a temperature sensor in a valley dip and it reads colder than the one in my garden by a few degrees yet each sensor are only about 100 feet away from each other, the difference is far more noticeable on clear cold nights but they both read similar through the daytime.

 

So it just depends on local topography of how the land is shaped and how "sheltered" a place is like a river valley etc. Also If you live in a very built up area like a city centre or close to a town centre you will have warmer temperatures in that regard because of the "urban heat island"

For where I live during uni holidays, in the Otter valley, east Devon: 

In terms of air frost, probably late October or early November on average, though in 2010 I had air frost on the 26th September.. min temp -0.1c.

 

2007: 12th November (evening)

2008: 22nd October

2009: 30th November (evening)

2010: 26th September

2011: 7th November

2012: 27th October (evening)

 

quite varied though as you can see.. one time late September and the previous year we had to wait until the night which took us into December.

 

For ground frosts it's earlier of course, September often gets within a few degrees of freezing, though I have no official way of recording ground frost.. however we had 3.0c on the 30th August 2010 and I saw a touch of frost in places! This year we got 4.2c in September at home so are probably still waiting.

On average probably late September, or perhaps early October.

Here near Egham it will be later in the year, as unlike home I'm not in any kind of valley or frost hollow. Not sure exactly when on average though.
