When do you think your first frost of the season will be? (nights, city)

[dunno what to put here]

0.1 days at Castlederg, which equates to one day every 10 years.

To my knowledge, the following places have recorded an air frost/freeze already:

Altnaharra
Aboyne
Redesdale Camp (only non-Scottish station)
Tulloch Bridge

Redesdale Camp recorded its first air frost/freeze on 31 August last year.

Castlederg 0.4c last week. Grrr

Freezing weather sounds very appealing right now as I sit in a hot and stuffy room with broken A/C.

It's always a shock isn't it? Usually it just comes up out of nowhere and everyones like .

It's a bit like aliens have arrived.

It's the same with the first snow, it just randomly starts to come.

I don't usually find it much of a shock. There will generally be a few nights in the 1-3C range, in the weeks leading up to the first frost

I predict my first freeze (or "air frost") will occur sometime in the first half of November.

Fall 'Freeze' Probabilities (Jul. 31 - Dec. 31)

50% chance of "air frost" before Oct 1. Ground frost may be earlier, but it's hard to tell. The chance of getting the first air frost after Oct 15 is low, < 10%.

Agree for "some" areas.

Here's NY's first frost dates. Many areas are in September.



Here's the U.S "freeze" average. So one can say frost would happen a bit sooner. Look at Maine, New Hampshire, Southern Vermont, and higher elevations of NY & CT "by October 1st". That means frost is possible in September there.

Chicago's first frost occurs between October 21st and 31st, however in the suburbs away from the lake it's earlier usually between October 1st through the 10th.

My hometown (Long Island) is after Nov 10! Similar to many oceanic climates! I always like to think we had a bit of oceanic-ness to our climate, about as good as you can get anywhere in the northern US.

Probably October.

Well here usually it is about 8c one night and hen it will drop below 0c. There is no clue etc that it is coming. It just randomly comes.
