Then the UK can manage 30°C - look at Bermuda. Not sure that I'd call Bermuda "offshore" Well, it's certainly not onshore. |

Altitude = Mountains/Plateaus/Whatever... Ie. Snow is more likely to occur in the mountains due to the higher altitude. Temperature extremes in NZ are set at about the same elevation as the UK. I was thinking of those places with reliable snowfall in the mountains. Since you like going by extremes, these are the modern records: Highest temp: 42.4 °C (NZ) 38.5 °C (UK) Lowest temp: -27.2°C (UK) -21.6 °C (NZ) British Isles actually have a larger temperature range at lower elevations. |

And that is the problem right there—using modern records for New Zealand's cold temperatures. New Zealand, alongside Australia and the rest of the South Pacific region, have markedly warmed up in their winter temperatures over the past century or so. If you head back to 1902, you will find that New Zealand recorded –25.6° C at Eweburn (now Ranfurly), at an elevation of a mere ~430 m AMSL, which is not much higher than the likes of Braemar; but, it is at a much lower latitude. |

There's a reason for using modern records, they're considered more reliable, and the climate has changed. The UK records stretch back over 300 years, but we only quote 1914 onward, and usually only back to the 1960's for extremes. Even the reliability questions aside, for the purposes of this discussion, it's pretty pointless to quote a temperature that was recorded in 1903, which NZ hasn't even come within 4C of in the last 116 years, and was recorded 100m higher than any UK station. Climates have changed, measurements have become more reliable. |

Climates have changed, measurements have become more reliable.There's nothing to suggest the record is unreliable, although RWood would best best to explain it further. 100m pretty is insignificant in terms of climate Even without extremes or altitude, NZ has towns that are warmer, colder, wetter and drier than the UK -there's just more variation.
Besides, your point was that the UK and NZ records were recorded at similar altitudes, that's incorrect. The NZ low you're referring to was set at 430m. The UK record of -27.2C was recorded in 1995, at 80m, in Altnaharra. We're talking a 350m difference right there.
What are the coldest towns in NZ? |

The fact that no temperature recording has come close to it in over 100 years makes it seem questionable, or at the very least it's no longer relevant. The UK's record low is extremely reliable and relevant because it's been matched or nearly matched on several occasions. Besides, your point was that the UK and NZ records were recorded at similar altitudes, that's incorrect. The NZ low you're referring to was set at 430m. The UK record of -27.2C was recorded at 80m, in Altnaharra. We're talking a 350m difference right there. What are the coldest towns in NZ? Aye, but ain't that a frost hollow? Braemar, at 339 m AMSL, also recorded that very temperature of –27.2° C. Eweburn's record of –25.6° C in 1903 was due chiefly to cold-pooling as a result from tremendous snowfall, located on a high, flat tableland as opposed to a frost hollow valley such as Altnaharra; of course, the frost hollow would see greater plummeting in terms of low minimum temperatures. New Zealand's cold record has not even been slightly approached in recent decades, which owes to the plain notion that the subtropical ridge has now steered much farther south than it used to lie. |

New Zealand's cold record has not even been slightly approached in recent decades, which owes to the plain notion that the subtropical ridge has now steered much farther south than it used to lie. Potentially, but it's also next to a large Loch which would negate some of that, it also benefits from being the most northern inland station in the UK. Braemar has also recorded -27.2C on two separate occasions, and I think is the only station to go below -20C in 5 separate months; November, December, January, February, March. Altnaharra is a much younger station, probably has some colder temps that weren't recorded. Quite a consistent performer, been below -20C several times in the last decade. |

D-. The only thing that saves it is the reasonable sunshine.

Pretty similar to my hometown of Christchurch but perhaps even more boring as it looks to have less variation in temps (ChCh can get unseasonably warm days due to foehn winds and is generally less moderated by the sea). I'll give it a D-. It's very boring, but at least you won't die or be severely inconvenienced by the weather here.
