« on: September 18, 2018, 11:10:30 AM »
July 1969: Pressures were high over New Zealand in July, and rainfall was below average over almost the whole country. In the North Island the weather was unusually frosty. Feed shortages were reported in most districts of both islands. In parts of Canterbury the ground was too dry.

Rainfall:
Rainfall was mainly half the average value. Over the greater part of North Otago and South Canterbury, Central Marlborough and the Waimea plains of Nelson it was less than a quarter. Oamaru received a total of only 0.10”. The only areas with rainfall close to or somewhat above average were Fiordland with part of South Westland, and northern Wairarapa.

Temperatures: Over the greater part of the North Island, temperatures were more than 2F below average. On the other hand, in many inland districts of the South Island and in coastal Southland they were 1F-3F above average. On the 23rd, in a general northerly flow, some unusually low relative humidities were recorded in Canterbury. At 9am value at the Hermitage was 7%; at Glentanner 8%; and at Highbank power station, 7%.  Snowfalls to fairly low levels were reported in Southland and West Otago, Banks Peninsula and Wairarapa on the 1st-2nd; in mid-Canterbury and the central North Island from the 9th-11th; and in the Gisborne high country on the 19th-20th.

Sunshine: Sunshine was above average in northern and eastern districts of the North Island by 20-50 hours. Parts of Northland were especially favoured, Kaitaia receiving 186 hours. In the Wanganui-Manawatu area and also in Buller sunshine was 20 hours below average.
