NZ weather summary August 1982
« on: May 19, 2012, 02:16:06 PM »
August 1982:  August was generally a dry, sunny month that was slightly cooler than usual in the North Island but milder in the South Island. In the north winds were generally lighter than usual and south-westerly winds were much more frequent than normal. South-westerlies were also very frequent in the south and Invercargill had its greatest frequency of both south-westerly winds and strong winds since 1964. Gale force winds and thunderstorms were widespread on the 2nd as an active front crossed the country, and a tornado at Netherton (near Paeroa) caused some damage locally.

Rainfall: It was a very dry month in the North Island, with most areas recording less than half their normal rainfall. Many eastern areas and parts of Northland had less than 20% of the usual rainfall. Rainfall totals for the North Island for the year to date are between 70% and 90% of normal, with central and southern areas having the greatest departures. Lake levels are consequently very low for this time of year. In the South Island most northern and eastern areas had less than half their normal rainfall. The driest areas were the Kaikoura Coast, where 10%-25% of normal was recorded, and coastal Canterbury where 20%-50% was received. Drought conditions continued in these areas, which have had only 50%-70% of their usual rainfall for the year to date. In contrast southern Westland, Fiordland, Southland and Central Otago had above average rainfall, with some parts of Central Otago recording more than twice their usual August rainfalls.

Some totals (mm): Otira 595, Cropp Waterfall 1021, Milford 697, Queenstown 100, Earnscleugh 43, Invercargill 97, Stewart Is 176; Kerikeri 19, Albert Park 33, Rotorua 24, Taupo 17, New Plymouth Aero 59, Ruatoria 15, Lower Hutt 48, Blenheim 14, Grassmere 5, Christchurch 15, Oamaru Aero 8.

Temperatures: Average temperatures in the North Island were between normal and 1.0C below normal in northern areas and up to 0.5C above normal in the south. August was relatively mild in the South Island, with most areas averaging about 1C above normal, and parts of Canterbury 2C above. This was mainly due to high daytime temperatures, these being up to 3C above average. Some high temperatures were recorded during a warm spell between the 22nd and 25th. On the 24th 22.1C was recorded at Ashburton, 21.9C at Timaru and 21.4C at Hororata.

22.1C maximum at Ashburton on the 24th, -9.0C minimum at Tekapo on the 19th.

Sunshine:  August was generally sunny, with the only areas to record less sunshine than usual being the west coast of the South Island and Southland. Eastern areas and Taranaki were particularly sunny, with Gisborne having its highest August total (records from 1937), Masterton its highest since 1935 and Christchurch its 2nd highest (records from 1949).

[Some totals: Kaitaia 178, Waitangi 167, Whangarei 152, Leigh 159, Auckland 150, Tauranga 176, Whakatane 187, Rotorua 153, Taupo 142, Auckland Aero 153, Hamilton 149, New Plymouth 184, Masterton 177, Dannevirke 150, Gisborne 200, Napier 195, Wairoa 189, Paraparaumu 160, Ohakea 140, Palmerston North 119, Levin 126, Wellington 175, Stratford 178, Wanganui 147, Westport 105, Arapito 105, Hokitika 114, Greymouth 86, Nelson 199, Blenheim 203, Grassmere 201, Kaikoura 189, Mt Cook 116, Methven 170, Christchurch 190, Timaru 172, Oamaru Aero 154, Omarama 165, Palmerston 135, Dunedin Aero 136, Dunedin 126, Te Anau 118, Queenstown 107, Cromwell 152, Alexandra 151, Gore 132, Invercargill 106].

After a cold dull start to winter in June, Wellington had very high sunshine totals in both July and August, well worth the price of a few nippy nights.
