NZ weather summary August 1983
« on: April 27, 2012, 08:59:49 AM »
August 1983:  August was a mild month with less rainfall than normal in most parts of New Zealand. Pressures over the country were 4 to 5mb higher than normal. North-westerly winds were more frequent than normal over the North Island, while south-westerlies were unusually frequent over the South Island. Heavy rain on the 2nd and 3rd caused some localised flooding at Wakefield (near Nelson) and rain also disrupted rush hour traffic in Wellington. On the 13th and 14th heavy snow fell in central North Island areas resulting in the closure of the Napier-Taihape and Napier-Gisborne roads. Farmers in most northern and eastern districts reported dry conditions with little growth.

Rainfall: As a whole the country received less rain than usual, although Paraparaumu and parts of Westland, Southland, Otago and the Alps, recorded rainfalls close to, or slightly above average. Northern and eastern areas of both islands generally received less than half their normal August rainfall. Tauranga, Napier and Kaikoura recorded less than 30% of average; Tauranga and Napier had only slightly more than the record lows of August 1982.

Some totals (mm): Hawea 80, Te Anau 115, Alexandra 23; Albert Park 54, Tauranga 39, Waipukurau 17, Napier 31, Wanganui 37, Kaikoura 11, Oamaru Airport 10.

Temperatures: Temperatures were generally close to or slightly above average. Northern and central parts of the North Island, and southern and eastern South Island areas recorded monthly mean temperatures 0.5C to 1.0C warmer than usual. Remaining areas experienced near-normal temperatures. Apart from a cool period from the 5th-7th, temperatures were mild between the 1st and 11th. The following 7 days however were cold, with some heavy snowfalls in the central North Island. Between the 19th and 22nd daytime temperatures were generally below average, but with mild nights in most areas. The last 9 days of the month saw a return to cooler conditions.

21.4C
maximum at Hastings on the 1st, -6.2C minimum at Molesworth on the 27th.

Sunshine:   Most North Island areas received slightly less sunshine than normal during August, although Kaitaia, Auckland City, and the Bay of Plenty and Taranaki regions recorded average or slightly above average totals. Cloudier than usual conditions were experienced in coastal Southland and Otago, while the remainder of the South Island had sunshine totals close to, or slightly higher than normal.

[Some totals: Kaitaia 155, Waitangi 126, Whangarei 119, Leigh 145, Auckland 155, Tauranga 164, Whakatane 159, Rotorua 146, Taupo 121, Auckland Aero 138, Hamilton 129, New Plymouth 167, Masterton 107, Dannevirke 98, Gisborne 132, Napier 137, Wairoa 121, Paraparaumu 136, Ohakea 122, Palmerston North 81, Levin 115, Wellington 119, Stratford 151, Wanganui 114, Westport 131, Arapito 119, Hokitika 143, Greymouth 134, Nelson 200, Blenheim 181, Grassmere 177, Kaikoura 182, Mt Cook 117, Methven 156, Christchurch 156, Timaru 147, Oamaru Aero 140, Omarama 171, Palmerston 130, Dunedin Aero 121, Dunedin 96, Te Anau 117, Queenstown 117, Cromwell 169, Alexandra 155, Gore 132, Invercargill 105, Campbell Is 11 {3rd lowest}, Chatham Is 68 {3rd lowest}].
