October 1971: October was marked by an unusually high frequency of northwesterly winds. It was a wet month, and in parts of the North Island, too wet for farmers. Conditions were better in the South Island, with good growth. Violent northwesterly gales buffeted parts of Otago on the 27th, with a gust to 98mph at Dunedin Airport.
Rainfall: Rainfall was above normal over nearly the whole of the North Island and over the South Island except for Banks Peninsula and the Canterbury Plains north of Timaru, and parts of Otago and Southland. Marlborough, central and southern Hawkes Bay with parts of Wairarapa, and parts of the South Island high country received 2-4 times the normal value. The period from the 18th to the 24th was particularly wet over the North Island during the passage of 3 deep depressions. The second of these brought falls of up to 200mm to Wairarapa and Marlborough on the 20th; and the third brought falls of up to 300mm to central Hawkes Bay on the 23rd, with serious flooding.
Some totals: Taumarunui 245mm, New Plymouth 203mm, Chateau Tongariro 459mm, Napier 165mm, Stratford Mountain House 912mm, Milford 848mm, Taieri 19mm.
Temperatures: Temperatures were mainly close to normal. However, in some eastern districts from Timaru to Napier and in parts of Wellington and Manawatu they were 0.5C above normal; while in the Canterbury high country and parts of Buller and Nelson they were the same amount below normal.
27.0C maximum at Bromley, Christchurch on the 17th.
Sunshine: Sunshine was close to normal except in northern Northland, Wairarapa and the Thames-Bay of Plenty area [also in Nelson and central Marlborough], where it was up to 30 hours below normal.
