November 1966: November was cloudy and cool, and also wetter and more unsettled than usual. The additional rain was appreciated after the comparatively dry weather of September and October in most areas. However, unsettled conditions delayed shearing, especially in the North Island.
Rainfall: Rainfall was more than double the average value in parts of Nelson and Bay of Islands. It was also well above average in central Canterbury, central Hawkes Bay, and parts of eastern Northland, Auckland, Taupo, Wanganui and Central Otago. Elsewhere rainfall was fairly close to average, though predominantly somewhat greater. On the afternoon of the 18th a thunderstorm in Christchurch was accompanied by hail and unusually heavy rain. In parts of the city as much as 1.5” of rain were recorded in half an hour, with street flooding.
Temperatures: Temperatures were mainly 1F-2F below average. There were two cold spells, about 5-12 and 19-23 November, with snow well down on the ranges.
S
unshine: Over the greater part of the North Island and most inland districts of the South Island sunshine was 20-50 hours below average. In coastal districts of the South Island and also in Southland, Taranaki, Gisborne, Auckland and Northland, it was close to, or a little below, average [average or better in Westland, near normal in Manawatu-Horowhenua].
