Title: NZ weather summary May 1966
Post by: Rwood on July 05, 2018, 04:01:24 PM
May 1966: Barometers were low over and to the east of the North Island, and there was an unusually high frequency of southerly to easterly winds. It was a cold month but conditions were particularly pleasant on the West Coast. Farmers found it a good month for stock, though growth was affected in some areas by frosts, and in Northland and Auckland the ground was becoming rather too wet.

Rainfall: On the West Coast it was by far the driest May on record, with less than 1/4 of the average rainfall. It was also exceptionally dry in the Alps, the Canterbury high country, and Central Otago. Rainfall was also somewhat below average in Southland and Nelson and in the North Island west of the main ranges from Hamilton and Opotiki to Levin. In eastern districts from Oamaru to East Cape, about Cook Strait, and in Northland and Auckland rainfall was above average. The surplus exceeded 50% in Wairarapa, Wellington, most of Marlborough and the North Canterbury coast, also in Coromandel. Over most of Marlborough 2/3 of the month’s rain, amounting to 4-10” fell on the 23rd during the passage of a deep depression across the North Island. Flooding disrupted road and rail transport on the Kaikoura Coast.

Temperatures:
Temperatures were mainly below average by about 1F-2F, highest departures being in Manawatu. On the West Coast they were close to average. The second half of the month was much colder than the first half. Two spells of cold southerlies brought snow to the ranges and some of the North Island high country form the 17th-20th and on the 25th-26th, respectively.

Sunshine: Northern and western districts of both islands together with parts of Southland were favoured with more sunshine than usual, mainly by 20-30 hours. Eastern districts from Balclutha to East Cape were less than average by a similar amount.

Cool but sunny and pleasant for many parts. A grey bleak month in Dunedin.
