Re: Only a Brit could believe it's possible to be without heating for a week in the winter
New Zealand has a mild and temperate maritime climate (Köppen: Cfb) with mean annual temperatures ranging from 10 °C (50 °F) in the south to 16 °C (61 °F) in the north.
That represents spring and autumn in the Nordic counties. Winter is below zero C.
This would be a normal mild winters day in Finland (disappearing as it is):
"the township of Ranfurly in Central Otago holds the New Zealand record for lowest temperature with a reading of -25.6 °C on 18 July 1903.
Winters in southern Finland (when mean daily temperature remains below 0 °C or 32 °F) are usually about 100 days long, and in the inland the snow typically covers the land from about late November to April, and on the coastal areas such as Helsinki, snow often covers the land from late December to late March. Even in the south, the harshest winter nights can see the temperatures fall to −30 °C (−22 °F) although on coastal areas like Helsinki, temperatures below −30 °C (−22 °F) are very rare.
In northern Finland, particularly in Lapland, the winters are long and cold, while the summers are relatively warm but short. The most severe winter days in Lapland can see the temperature fall down to −45 °C (−49 °F).
