Central Otago Hoarfrost

The Central Otago region town of Alexandra is around the size of Cooma and about 50 kilometres from Wanaka on the road to Dunedin. It lies in a valley on the Clutha River which runs out of Lake Wanaka. During the winter the valley gets severe frosts followed by cloudy days which keep the temperature just above zero. Hence the frost builds on the frost to give you hoarfrost. This may last for a week or more.
