NZ weather summary September 1971
« on: March 17, 2012, 12:59:46 PM »
September 1971: In contrast with previous months, September was marked by a greater frequency than normal of winds from a westerly quarter. It was also a warm month, especially in the east. Farmers found the weather too wet over the greater part of the North Island. On the other hand, in parts of Canterbury it was too dry. Unusually violent northwesterly gales buffeted Canterbury and Otago on the 10th-11th, with considerable damage in some inland districts.

Rainfall: Rainfall was above normal over the North Island north of Paraparaumu and Masterton; and in the South Island on the West Coast and in the Alps, and in Southland and most of Otago. In Waikato and parts of Bay of Plenty and in central Hawkes Bay it was more than double the normal value. In Nelson, Marlborough, most of Canterbury, and North Otago rainfall was below normal, being less than half in some coastal districts from north of Timaru to west of Nelson city.

255mm rainfall at Whakatane, 403mm at Te Teko, 212mm at Hamilton, 856mm at Milford Sound, 4mm at Cape Campbell.

Temperatures: Temperatures were 1C above normal in eastern districts of both islands but close to or only slightly above normal in the west.

25.0C maximum at Christchurch on the 11th, -7.3C minimum at Hanmer on the 30th.

Sunshine: West of the main ranges from Waikato to Manawatu sunshine was 20-50 hours below normal. It was also below normal on the Southland coast and in the Bay of Plenty. Totals were up to 20 hours above average in parts of Northland, Nelson, Marlborough and the Mackenzie area.

A reversion from the high frequency of easterly-northeasterly winds in earlier months. Nevertheless it was cloudier than average in the Bay of Plenty while Westland had normal sunshine.
