NZ weather summary October 1969
« on: September 27, 2018, 06:01:24 PM »
October 1969:  This was the driest October since 1963, besides being sunny and cool. Over the greater part of the country 1969 has been a dry year so far, and this was particularly noticeable in March, July and August, in addition to October. For most farmers dry frosty weather has resulted in rather poor growth, and good rain would now be appreciated in all farming districts except Southland. Strong gales buffeted Otago and Canterbury besides Cook Strait on the 26th, causing some damage.

Rainfall: Rainfall was below average, except in Southland and in a small area of northern Hawkes Bay and Gisborne. It was less than half the average value in northern and central districts of the North Island, in Nelson and Marlborough, and in parts of inland Canterbury. In eastern Northland, Coromandel, and parts of Bay of Plenty it was less than a quarter. The only area with rainfall more than 50% above average was around Foveaux Strait.

Temperatures:  Mean temperatures were 1F-2F below average. The 10th was an unusually cold day in eastern districts and about Cook Strait, with snow showers to low levels.

Sunshine: The greater part of the country was favoured with 30-80 hours more sunshine than average. Largest surpluses were recorded in Taupo and Hawkes Bay, about Cook Strait, and at Waimate and Oamaru. Blenheim received 300 hours, the highest ever recorded in New Zealand in October. In eastern Northland and northern Waikato and on the Southland coast sunshine was 20-40 hours below average.

[Some totals:  Kaitaia 177, Kerikeri 145, Whangarei 138, Auckland 170, Tauranga 227, Whakatane 251, Taupo 230, Opotiki 238, Hamilton 186, New Plymouth 187, Masterton 208, Gisborne 248, Napier 265, Wairoa 235, Paraparaumu 196, Ohakea 199, Palmerston North 170, Levin 166, Wellington 229, Stratford 209, Ohakune 154, Wanganui 196, Takaka 253, Westport 167, Hokitika 194, Greymouth 148, Haast 193, Riwaka 276, Nelson 274, Blenheim 300, Grassmere 257, Kaikoura 226, Mt Cook 169, Mt John 252, Methven 221, Christchurch 211, Tekapo 258, Timaru 212, Waimate 209, Omarama 239, Palmerston 224, Dunedin Aero 198, Dunedin 182, Oamaru 224, Queenstown 222, Alexandra 221, Invercargill 140, Raoul Is 233 {equal highest}, Campbell Is 57, Chatham Is 165]

A cool, dry and sunny month. Blenheim's record October total still stands, with not even any of the optimistic readings from electronic sites matching it yet. Wellington's October was much pleasanter than usual, due to a lack of NW winds.

Another one of those months where the Stratford reading is higher than New Plymouth's.

This was late in the life of the NP instrument (stopped 1973, with Aero starting in 1972), and I suspect that there was some deterioration (surroundings, glass sphere, sun card inconsistencies, etc. etc) in the latter years. This seems to have happened to some degree at many sites, most likely with the instrument in many cases). When the Aero site started it was at least 75-100 hours per year sunnier than the city one.

October 1969:  [/color]The 10th was an unusually cold day in eastern districts and about Cook Strait, with snow showers to low levels.


Read about that day on a Chch Press microfilm, and the article about the cold snap stated that Kaikoura's maximum on the 10th was only 40F (5C), it's coldest for any month for 15 years, while Chch only reached 42F (6C) in the afternoon, and there were snow showers in the city in the morning. The cold southerly we've just had was certainly unseasonable, but definitely not as wintry as 10th October 1969.

That is pretty miserable for October, for sure.

However it was short-lived - Wellington benefited from a relative lack of NW & SE winds, and with more sunny days than usual for October it was a much more pleasant month than most of our Octobers.
