Midway Island, 28N, record low of 54F. Warmer then Key West, 23N, record low of 41F.
Corpus Christi, Texas is the same latitude with a record low of 12F.
I have a question. It is common knowledge (well, among weather geeks) that the Siberian High makes winters in East Asia very very cold (given a location's latitude). The Siberian High is usually positioned over Mongolia or Eastern Siberia.
In North America, there is an analogous, though much weaker anticyclone called North American High. But I know much less about it. Where does it usually sit? Does it occur every winter? Does it move around? All I know is that whenever there is a high pressure system over eastern Canada (usually central Quebec), arctic air comes down to Northeastern US and creates really bad cold snaps.

From what I understand, I think the North American high generally settles in between 55-65N latitude in the Northwest Territories/Northern Saskatchewan and Manitoba and moves east and south and sometimes west during cold snaps during the winter. I think it occurs more or less every winter but its strength is variable from year to year.
We all know about the gulf stream and its effect on Florida and Northwest Europe. But what are some other examples of climates that are exceptionally warm (or cool) for their latitude (or altitude) and what are the reasons for these anomalies?
Vladivostok has an annual mean of about 4.5 C / 40 F compared to the 10 C / 50 F mean that would be expected at 43 N. This appears to be mainly due to the effect of cold ocean currents.
Wikipedia has an interesting note: "The waters of the Oyashio Current originate in the Arctic Ocean and flow southward via the Bering Sea. The current has an important impact on the climate of the Russian Far East, mainly in Kamchatka and Chukotka, where the northern limit of tree growth is moved up to ten degrees south of the latitude it can reach in inland Siberia."
Vladivostok is nowhere near Chukotka and the Bering Sea/Strait.
Vladivostok's annual mean temperature (and climate) has two controls (like Korea):
1. Tropical moisture from the Pacific in summer.
2. Cold and dry air from Siberia/Asia in winter.
Kamchatka is completely different from Vladivostok or Khabarovsk. Kamchatka has much cooler summers and milder winters. So, the ocean does play a pretty major role on that peninsula. Also, Kamchatka has a pretty even distribution of precipitation over a year. Vladivostok and Khabarovsk are extremely dry in the winter and very wet in the warm summer months.
Eastern Asia has some of the most interesting climates on this planet I'd say...Khabarovsk saw a 95F/78F day last June and a -16F/-32F day last January.

Interesting. I'd rather it just stay in the Northwest Territories and not move east and south.

But Vladivostok has very low winter SSTs... or is that also a consequence of Siberian air masses?

Vladivostok is impressively sunny in winter for their latitude, but oddly, very cloudy in summer.
% chance of sun seems lower in summer.
Their winter months are far colder than Toronto's,
but Nov and March avg temps are roughly equal; yet Vlad blows away Toronto for sunshine.
UV maxes also show this seasonal lag in UV maxes; Aug is higher than Jun.
(^^ still have no replies to my recent UV max thread btw. )
It would be hard to parse the relative importance of the Oyashio Current vs the Siberian High. My guess is that Sakhalin Island and Hokkaido shield the Sea of Japan from the full effect of the cold current (just like Newfoundland and the Grand Banks shield Northeast the Labrador current).
Vladivostok is the southernmost port to freeze regularly in the winter.
Shanghai in China has a cold climate for 31 degrees from the equator.
Yearly mean is only 13 - 20C.
It has a hot and humid summer, but long and cold winter for a place thats equivalent in latitude to about Perth in WA, or Port Macquarie on the east coast here.
Very continental climatefor a coastal place, which probably stops the winter from heading into true subzero readings. Shanghai - Wikipedia, the free encyclopedia
