It was also cooler than usual in many other North Island and southern and western South Island regions. Temperatures were near average in Coromandel, western Bay of Plenty, Hawke’s Bay, Wellington, Nelson, Marlborough, and Canterbury. The November national average temperature of 13.2 °C was 0.6 °C below normal. At Clyde, in Central Otago, it was one of the coolest Novembers in the last two decades.
