NZ weather summary November 1957
« on: May 04, 2018, 02:52:11 PM »
November 1957: Like the previous month, it was unusually windy. It was also much wetter and cloudier than usual in most districts. Growth was affected in the South Island, and shearing delayed in many areas. On the 25th a strong northwesterly gale caused damage in Wellington, Wairarapa, and Canterbury.

Rainfall: Rainfall was well above normal, except in northern and eastern areas of the North Island. Around Lake Wanaka and in parts of Central Otago it was more than 3 times as wet as usual, and a few stations had their highest rainfall for any month on record. To the north and west of the lake totals ranged from 20” to 26”. For Invercargill City, it was the wettest November in over 30 years, with 7.43”.

On the other hand, the Gisborne-East Coast district had less than half the average rainfall. Following heavy rain in the Lakes District from the 14th to 20th in northwesterly conditions, major floods were reported in the Clutha and several Southland rivers. At the foot of Mt Aspiring, 14.2” were recorded from the 16th-20th, of which over 8” fell on the 18th. Many thunderstorms were reported on the West Coast from the 23rd-28th, and at times they extended to other districts as far north as Taranaki and Hawkes Bay. Large hailstones exceeding 1” in diameter were reported at Maronan, west of Ashburton, on the 14th, and at Barrytown on the 26th.

Temperatures: Temperatures were mainly close to normal. However, eastern districts of the North Island were 1F-3F warmer than usual, while the South Island high country and Central Otago were 1F-2F cooler than normal. High temperatures were recorded in eastern districts from the 17th to the 19th, with Christchurch Aero and Ashburton both exceeding 89F (32C). Falls of snow were reported on the ranges of Otago and Southland at the beginning of the month and again on the 27th.

Sunshine: Sunshine was below normal by 1-2 hours per day, except in the provinces of Auckland and Hawkes Bay. The only area favoured with appreciably more sunshine than usual was Northland and Auckland City.

 [Some totals: Te Hapua 201, Kaitaia 212, Kerikeri 241, Whangarei 229, Auckland 220, Tauranga 232, Whakatane 244, Taupo 213, Hamilton 213, New Plymouth 156, Masterton 196, Gisborne 233, Napier 234, Paraparaumu 143, Ohakea 176, Palmerston Nth 144, Levin 119, Wellington 147, Wanganui 198, Westport 142, Hokitika 145, Greymouth 131, Haast 133, Nelson 196, Blenheim 212, Grassmere 204, Mt Cook 98, Methven 166, Christchurch 160, Tekapo 188, Timaru 160, Waimate 141, Omarama 162, Dunedin 127, Queenstown 162, Alexandra 154 (equalling the previous November’s record low), Invercargill 137, Raoul Is 253, Campbell Is 109, Chatham Is 147].
