NZ weather summary December 1984
« on: May 09, 2012, 03:10:00 PM »
December 1984: December was generally a remarkably warm month, but cloudy in the South Island. North-easterly winds were more frequent than usual, with winds from this quarter being the 2nd highest for December in both Auckland and Invercargill since recording began in 1956. There were fewer southerly quarter winds than usual in Auckland and fewer westerlies, especially north-westerly, in Invercargill. Gale force winds on the 19th felled many trees, and caused widespread power cuts and losses of cut hay in Canterbury and North Otago. Pressures were lower than usual this month especially in the north and west. A notable feature this month was the high number of electrical storms – these were recorded in some part of the country on all but 3 days, and parts of Northland and Westland had up to 10 such storms this month. There was a particularly severe storm in the Auckland-Hamilton area on the 16th during which a linesman was killed at Te Awamutu, and two people hospitalised after being struck in Otorohanga and Puketaha. The accompanying heavy rain caused $500,000 of flood damage in Auckland City.

Rainfall:
The only areas to record average or below average rainfall were isolated areas around Kaitaia, southern and eastern areas of the North Island and parts of South Canterbury and Otago. Parts of Gisborne and Wairarapa were very dry, with stations recording between 40%-60% of normal rainfall. The rest of the country had more rain than average, the north and west of the South Island being particularly wet. Much of Nelson, Marlborough and Westland had over 200% of normal, while parts of South Westland had 300% or more. Among some of the higher totals (% of normal in brackets) were Franz Josef 1373mm (325%), Fox Glacier 1079mm (276%), Haast Pass 934mm (287%) and Bruce Bay 762mm (260%).

Some totals (mm): Whangarei 193, Albert Park 197, Te Puke 270, Ruakura 188, Stratford 218, Hokitika 349, Cropp Waterfall 1951, Milford 870, Nelson 169, Blenheim 124, Mt Cook 925, Tekapo 137, Queenstown 123; Masterton 38, Gisborne 52, Wellington Aero 49, Ashburton 37.

Temperatures: December was warmer than usual everywhere except in the high country of the South Island and Central Otago. These areas had between average and 1.0C below average temperatures. Other areas in the South Island were up to 1.5C above average. Temperatures in the North Island were uniformly very high, ranging between 1.5C and 3.0C above average. Central and eastern areas were warmest with many stations recording mean daily temperatures 2-3C above average and new mean daily temperature records established at many sites. These included (year records started in brackets) Gisborne (1937), Kaitaia (1941), Taupo (1949) and Paraparaumu (1953). Napier had its hottest December since 1877.

32.2C
maximum at Northburn on the 31st, 0.6C minimum at Molesworth on the 9th.

Sunshine:   Most of the North Island had average or above average sunshine with central and southern areas recording 20-40 hours more sunshine than usual. The South Island was cloudier than average, especially in northern and southern districts, which had 40-60 hours less sunshine than usual. Blenheim and Dunedin recorded their second and third lowest December totals since recording began in 1930 and 1933 respectively. Among stations recording the greatest departures were Ruakura (+35 hours), Wellington (+24 hours), Auckland (+19 hours), Dunedin Airport (-58 hours), Blenheim (-41 hours) and Invercargill (-32 hours).

[Some totals: Kaitaia 209, Waitangi 213, Whangarei 204, Leigh 235, Auckland 247, Tauranga 231, Whakatane 233, Rotorua 226, Taupo 220, Auckland Aero 266, Hamilton 245, New Plymouth 231, Masterton 194, Dannevirke 199, Gisborne 231, Napier 216, Wairoa 214, Paraparaumu 250, Ohakea 259, Palmerston North 206, Levin 236, Wellington 244, Stratford 217, Wanganui 254, Westport 182, Arapito 176, Hokitika 183, Greymouth 183, Nelson 222, Blenheim 206, Grassmere 209, Kaikoura 192, Mt Cook 121,  Methven 195, Christchurch 196, Timaru 158, Oamaru Aero 133, Omarama 153, Palmerston 127, Dunedin Aero 119, Dunedin 121, Te Anau 147, Queenstown 162, Cromwell 175, Alexandra 173, Gore 157, Invercargill 152].
