NZ weather summary February 1968
« on: July 30, 2018, 04:50:28 PM »
February 1968: In the North Island this was the driest February since 1946 and one of the driest months on record. The weather was also sunny over both Islands. Northern districts were experiencing their 2nd successive month of very dry weather, and dairy production there was dropping with feed scarce in some parts. Elsewhere in the North Island and Nelson dry weather was beginning to affect pastures and crops, but it was a good month for harvesting. In Canterbury, Otago and Southland the feed supply was somewhat better than in the North Island.

Rainfall: Rainfall was mainly only 1/3 of the average value in the North Island. In Gisborne and parts of northern Northland it was less than 10% of average. Many parts of the North Island received little or no rain after the 9th. Other dry months over the North Island with about the same rainfall as February 1968 were February 1915, March 1931, January 1955 and January 1957. However in February 1946 totals were only about half as much as in February 1968.

Over the greater part of the South Island rainfall was close to average. It was only about 2/3 of average in most of Nelson, Marlborough, coastal North Canterbury, Otago and eastern Southland, and it was considerably lower – less than half – in the Waimea Plains, around Kaikoura, and in parts of inland North Otago. However, in Westland and northern Fiordland it was more than 50% above average.

Temperatures: Temperature were 1F-3F warmer than usual in the South Island, except on the West Coast, where they were cooler than usual by 1F-2F. In the North Island they were mainly close to average. The second half of the month was warmer than the first; and from the 20th onward some eastern districts recorded maximum temperatures of 90-98F at times.

Sunshine: Sunshine was above average, except on the West Coast, where it was close to average. The surplus was mainly 30-60 hours and was greatest in Northland and Auckland, in Gisborne, and in Nelson, Marlborough and Canterbury.

[Some totals:  Kaitaia 232, Kerikeri 229, Whangarei 233, Auckland 245, Tauranga 242, Whakatane 254, Taupo 234, Opotiki 258, Hamilton 200, New Plymouth 246, Masterton 235, Gisborne 260, Napier 247, Wairoa 256, Paraparaumu 227, Ohakea 253, Palmerston North 207, Levin 208, Wellington 247, Stratford 246, Ohakune 230, Wanganui 242, Westport 202, Hokitika 172, Greymouth 154, Haast 169, Riwaka 302, Nelson 271, Blenheim 298, Grassmere 259, Kaikoura 225, Mt Cook 168, Mt John 246, Methven 235, Christchurch 223, Tekapo 247, Timaru 219, Waimate 198, Omarama 242, Dunedin Aero 193, Dunedin 191, Oamaru 192, Queenstown 193, Alexandra 230, Invercargill 184, Campbell Is 106, Chatham Is 159].

A very sunny summer month. Riwaka's 302 hours is the highest recorded in NZ in February (though its total of 292 hours in February 1973 was actually a fraction sunnier in % of possible terms).

300 + hours in a month is a lot in NZ. The 1973 % -is that just the leap year business? Not a shift in station or change in shadowing from structures? Thanks.

A small difference due to leap year - about 81.6% 1968 vs. 81.8% for 1973 though that much accuracy is questionable. Later March 1969 gives similar %s for a different region ...

Thanks, RWood.
