NZ weather summary November 1975
« on: February 12, 2012, 01:28:03 PM »
November 1975:   November was a cool month marked by a comparative absence of the usual westerly weather and an unusually high frequency of wintry southerly conditions. Unsettled weather delayed some shearing and haymaking.

Rainfall: Rainfall was below normal over the greater part of the country by about 25%. However, it was mainly above normal east of the North Island ranges, in northern and eastern Northland, Auckland, Wellington, most of Marlborough, and parts of Nelson and Canterbury. Greatest relative excesses were reported in central and southern Hawkes Bay and on the Wairarapa coast. In the last-named area totals were 2-3 times the average. Thunderstorms with hail affected some eastern districts of both islands on the 8th and 12th. At Wigram, Christchurch on the 12th 27mm of rain fell in 20 minutes and 33mm in half an hour. This was the heaviest fall ever recorded in Canterbury for these two durations. Flooding and hail of diameter 1cm caused some damage in Christchurch.

Some monthly totals (mm): Masterton 110, Castlepoint 133, Napier 104, Blenheim 89; Whakatane 49, Paraparaumu 45, Milford 456, Queenstown 39, Cromwell 18, Invercargill 53.

Temperatures:  Temperatures were below normal from Hamilton southward except in the King Country and parts of Taranaki, and on the West Coast. The departures exceeded 1C in most of Canterbury and Marlborough, in Wellington and southern Wairarapa, and in most of Manawatu with parts of southern Hawkes Bay. The days most affected by relatively cold temperatures in southerlies were the 2nd-4th, 8th-10th, 14th-15th, 17th-18th, and 20th-23rd. On the 21st snow was reported to comparatively low levels in parts of the South Island and also on the road over the Rimutakas. The 22nd was a particularly cold morning in many districts, with air temperatures down to -4C at Twizel and Tara Hills, Omarama. [Warmer westerly conditions from the 24th].
 
30.3C maximum at Christchurch Airport on the 26th, -4.4C minimum at Moa Creek on the 22nd.

Sunshine:  Sunshine was mostly close to normal. However, it was below normal by 10-20% in a few areas, especially eastern districts from Whangarei to Thames, and Manawatu; and above normal by 10-14% over most of the Southland Plain and parts of Canterbury.

[Some totals: Kaitaia 196, Dargaville 176, Whangarei 174, Auckland 188, Tauranga 217, Whakatane 219, Taupo 191, Hamilton 215, Te Kuiti 168, Taumarunui 168, New Plymouth 191, Masterton 212, Dannevirke 174, Gisborne 225, Napier 211, Wairoa 204, Paraparaumu 175, Ohakea 202, Palmerston North 176, Levin 143, Wellington 223, Stratford 174, Wanganui 187, Westport 166, Hokitika 174, Greymouth 173, Haast 187, Riwaka 213, Nelson 218, Blenheim 234, Kaikoura 231, Mt Cook 133, Mt John 239, Methven 200, Christchurch 215, Tekapo 233, Timaru 197, Waimate 183, Omarama 203, Palmerston 187, Dunedin 168, Te Anau 196, Queenstown 198, Alexandra 218, Gore 174, Invercargill 192].

Seems that way. Interestingly, the SOI situation is quite different - in Nov 1975 we were still in a long-running La Nina which didn't fade till autumn 1976. The previous season(Nov 1974-May 1975) was very warm indeed, but the 1975-76 summer was very cold, and of course 1976 and 1977 were both cold years - El Nino turning up for the latter.
