Turku Rajakari since 2000:

Jajajajaja maybe I should make a Turku Botev weatherbox using Artukainen's highs and Rajakari's lows bro.
Helsinki Kaisaniemi,

I thought I would look at Ilomantsi Pötsönvaara too, but it hasn't recorded a June or August freeze, so it's not interesting enough.  I will do Utö instead...
Earliest: 13 October 1992

Umeå's University rooftop PWS vs the Airport station. A rooftop station is not subject to cold pooling unlike a large flat airfield a dozen meters below neighboring geography, since it's like 5m above the ground. The airport isn't exactly a "frost hollow" since a dozen meters isn't very huge, but it's enough to get a bunch of ground fog. The rooftop station is definitely not representative of most of Umeå, but maybe if you've got a hill somewhere, it's representative.

Normally early to mid October.
For 0C air temperatures:
Madison: October 8th, range September 12 to November 12
Milwaukee: October 22nd, range September 20 to November 24. Milwaukee is on the shores of Lake Michigan so it has some temperature lag and milder winters.
Average is 2000-2018, extremes are full POR

No freezes here, and that would have been unusually early. Also no freezes at the inland valley stations south of here. Røros inland at 625 m has of course freezes, as do some inland valleys further north at 65 N down to 140 m ASL. No freezes in most coastal areas, even in the Arctic coastal cities like Tromsø and Bodø. Average date for first freeze at Trondheim airport Værnes is Oct 9th.

I only voted December because the winters we do get freezes, they usually occur within a two week margin of Xmas, but it does not freeze regularly here. Our freeze on 1/2 this year was the first freeze we had in exactly 4 years (1/2/15 was the one before that)

Bar the odd year, it's pretty much always the last week of October, or first week of November for York.

I will do Utö instead...
