NZ weather summary August 1974
« on: March 28, 2012, 04:22:43 PM »
August 1974:  Pressures were low over New Zealand in August, and there was an unusually high frequency of winds from an easterly quarter, except in northern districts of the North Island. Persistent cloud and rain were reported in eastern areas, but on the West Coast of the South Island this was a sunny month with low rainfall. Conditions were too wet for farmers in eastern districts. On the 16th-17th heavy seas occurring with unusually high tides caused considerable damage in some eastern coastal places.

Rainfall: Rainfall was somewhat below normal over the greater part of the country. It was less than 1/4 of the normal value in Fiordland, most of Central Otago, and a considerable part of the Alps and inland Canterbury. Rainfall was above normal in most districts east of the main ranges besides eastern Bay of Plenty, Taupo, Manawatu, parts of Nelson and coastal Otago. In parts of central Canterbury, especially Banks Peninsula, totals were from 1 1/2 to 4 times the normal value.

327mm at Ruatoria, 260mm at Akaroa (the driest of 4 very wet Augusts there from 1973-1976); 2mm at Queenstown Aero.

Temperatures:   Temperatures were below normal by about 1C in Southland, Otago and most of Canterbury. They were above normal by up to 1C in Northland and Auckland and on the West Coast of the South Island. The coldest spells were from the 7th-12th, the 18th-20th, and especially the 23rd-26th, with snow well down on the high country of the South Island in this last instance.

Sunshine:   Sunshine was below normal, mainly by 30 hours, east of the ranges from Christchurch northward, and also in Nelson. It was above normal by up to 40 hours on the West Coast of the South Island and in Northland.

[Some totals: Kaitaia 179, Whangarei 171, Auckland 160, Tauranga 151, Whakatane 161, Taupo 125, Hamilton 145, New Plymouth 123, Masterton 114, Gisborne 132, Napier 138, Palmerston North 127, Levin 145, Wellington 125, Stratford 102, Wanganui 119, Westport 174, Hokitika 189, Haast 198, Riwaka 158, Nelson 151, Blenheim 167, Kaikoura 120, Mt Cook 133, Mt John 188, Methven 159, Christchurch 111, Timaru 143, Dunedin Aero 144, Dunedin 118, Queenstown 137, Alexandra 177, Invercargill 146, Raoul Is 180].
