NZ weather summary February 1976
« on: February 12, 2012, 08:27:21 PM »
February 1976:   Over most of the country this was the coldest February for at least 39 years, with 3 spells of particularly wintry weather. Pressures were higher than usual to the south, and there was an unusually high frequency of south-easterly winds. The month was also rather sunny, and very dry in some areas. In Northland and Southland farmers found conditions too dry, affecting crops and stock. Elsewhere cold temperatures retarded growth, and some vegetables were not ripening.

Rainfall: Rainfall showed unusually wide variations, from negligible amounts around Queenstown to four times the normal value around Napier and Hastings. It was below normal over most of the South Island and the greater part of the North Island. It was less than 25% of normal in the Southern Lakes district, parts of Marlborough and Nelson, and Northland south of the Bay of Islands. Rainfall was above normal over nearly all areas east of the ranges from Ashburton to the Kaikoura coast and from Cape Palliser to Wairoa. It was also above normal in the central North Island. On the 6th, hydro-electric stations on the Waikato from Arapuni to Taupo received 130mm-155mm.

269mm
at Waikaremoana, 0.4mm at Queenstown Aero.

Temperatures: Temperatures were below normal over the whole country, with departures of 1.5C-3.5C. Highest departures were recorded in an area extending from Wanganui and northern Manawatu to southern Hawkes Bay and northern Wairarapa.  To find a colder February it is necessary in most places to go back to 1937. In quite a few places however, it was the coldest February since 1931; and in Wellington the coldest since 1906. The most wintry spells were on the 7th-8th, 15th and 26th-27th. On the morning of the 27th New Plymouth Aero recorded its February ground frost in 40 years of observation.

32.0C max. at Ashburton on the 19th, -3.0C min. at Naseby on the 27th.

Sunshine: Northland, Auckland and Waikato were favoured with 50 more hours of sun than normal, and for some stations in these areas it was the sunniest February in 30-40 years of observation. Sunshine was also somewhat above normal in the King Country and North Taranaki, and over the whole of the South Island, particularly in inland South Canterbury.

[Some totals: Kaitaia 244, Auckland 246, Tauranga 239, Whakatane 248, Taupo 218, Auckland Aero 255, Hamilton 219, Taumarunui 197, New Plymouth 246, Masterton 183, Dannevirke 153, Gisborne 206, Napier 191, Paraparaumu 217, Palmerston North 168, Wellington 187, Stratford 211, Wanganui 202, Westport 201, Hokitika 196, Haast 215, Riwaka 249, Nelson 241, Blenheim 247, Kaikoura 207, Mt Cook 190, Mt John 274, planetchurch 217, Tekapo 266, Timaru 198, Oamaru Aero 205, Dunedin 184, Te Anau 214, Queenstown 234, Alexandra 223, Invercargill 188, Raoul Is 108].

Februaries of 1906, 1937 and 1993 are those comparisons which of the latter was 2.1 below average, at least this is sunnier.
