Idioms for how cold it is?

[Overseasmom100]

Doing a list and Ive come up with these

It's brass monkeys
Arctic weather
Frozen to the bone
Like the death of winter
Like Jack Frost has been

If I'm in very familiar company I've been known to say "fuck me, my nipples could cut glass"

Colder than a witch’s undercarriage.
Cold enough to freeze the balls off a brass monkey.
Taters. (Potatoes in the mold = cold.)
Perishing.
Cold as charity.

A friend from Shropshire uses starving to mean cold. He said it was quite commonplace, but I’d never heard it before, so I assumed it was a regional thing.

Here they say 'It's breezed up' when it's actually -25C.

I am 1900 and frozen to death

Similar here in Maine - "It ain’t been this cold since Eighteen-hundred-and-froze-to-death."

Colder than the hairs on a polar bears chuff.
So cold nipples look like chapel hat pegs.
Oh no snow!
Variations on the brass monkey.

Knobbling is a Welsh favourite

'Cold as a wizard's wotsit' (my DF)
'Not exactly bloody sultry' (DGF)

It’s chapping out there (or just ‘chappers/chaps’)....I think this is a London thing, never heard it anywhere else

Witch’s tits or witch’s nips

Foundered! Thats one used a lot here " christ im foundered"

@Alanamackaree the brass monkeys were the rings the (cannon) balls sat on, and the cold weather contracted the brass so the balls fell off the ring

I saw a good one the other day.
It's Motown weather, it's 3 degrees and I've got 4 Tops on lol

Perishing
Nithered
Chillled to the bone.

I don't understand the 1900 one.

Coldy coldy custard, dip y’nose in the mustard!

In our house we have 'it's fucking brrr' and brrr-by mc-brrrr brrrrr'

Also 'it's -20 in Pershore' from a few years ago when it was the coldest place in the country one winter and the topic of conversation locally.

My dear old dad used to say 'cold enough to freeze the balls off a brass monkey' often shortened to just 'brass monkeys'

Nice and simple in our house:

“It’s cold as dick!”

(But then again, everything is described “as dick” ie “he’s old as dick”, “it’s hot as dick” DH is military and it’s some kind of shit phrase that originated at work, he’s brought it home, and it’s stuck!)

Colder than the ace of spades ♠️

Where I come from originally, up in the NE near Newcastle, when it got to about -25 degrees we would sometimes hear something like

'it's cold (pronounced caaaaa(l)d) enough to put a jumper on.'

A northerner mentioning the possibility of needing to wear something over their t-shirt indicates it is well below freezing.

Nippy,
Parky,
A bit caaaaaald, (with or without the 'l' depending on exactly which part of the NE you are from, )
A lot of the others already mentioned like Brass Monkeys etc.

I say it's chilly con carne when it's cold.

It's that cold I've just bumped into a brass monkey crying it's eyes out. (credited to Del boy)

It's fucking baltic!

"I'm bivvered" meaning I'm absolutely freezing (South West expression, possibly?)

It's fucking baltic
It would freeze the balls of a brass monkey
Would freeze the nips off ye out there
I'm foundered
