NZ weather summary March 1971
« on: March 16, 2012, 07:11:16 PM »
March 1971:  It was the 5th successive month with an unusually high frequency of winds from an easterly quarter over the North Island. In Canterbury and southern districts of the North Island it was too dry, with feed shortages in some areas and crops affected. Good rains in Southland in the second half of the month relieved dry conditions that had developed there.

Rainfall: Rainfall was only about half the normal value over the greater part of the country, and was less than 25% in the North Canterbury high country. Persistently low rainfall has been recorded on the West Coast for the last 5 months, the total of 25.39” at Hokitika from November to March being the lowest in over a century of observations. In Canterbury and the Alps rainfall has been unusually low for 3 months; Lincoln’s 2.61” being the lowest since 1939, and the Hermitage’s 12.92” the lowest since 1947. Rainfall was above normal in 3 main areas: the South Island from Timaru and Haast southward; eastern Northland, Coromandel and most of Auckland; and parts of Gisborne and Hawkes Bay. Along the east coast of Northland, around Warkworth and in Coromandel a large proportion of the rain fell on the 10th-11th in easterlies, with a depression centred near North Cape. Totals of up to 10.5” were reported, with considerable flooding.

13.59" rainfall at Glenbervie Forest (Whangarei); 0.24" at Cape Campbell.

Temperatures: Temperatures were 1C above normal in the South Island and close to normal in the North Island.

31.0C maximum at Rangiora on 31st.

Sunshine: Most of the country was favoured with more sunshine than normal, and departures of 50-80 hours were recorded in western districts. On the West Coast it was the sunniest March for 30-50 years.

[Some totals:  Kaitaia 212, Kerikeri 197, Whangarei 202, Leigh 204, Auckland 223, Tauranga 211, Whakatane 204, Taupo 197, Opotiki 191, Auckland Aero 220, Hamilton 198, New Plymouth 245, Masterton 206, Gisborne 185, Napier 195, Wairoa 192, Paraparaumu 260, Ohakea 239, Kairanga 236, Palmerston North 209, Levin 226, Wellington 241, Stratford 233, Ohakune 206, Wanganui 250, Takaka 238, Westport 217, Hokitika 246, Greymouth 213, Haast 222, Riwaka 243, Nelson 244, Blenheim 212, Grassmere 193, Kaikoura 182, Mt Cook 175, Mt John 232, Methven 182, Christchurch 184, Tekapo 231, Timaru 179, Waimate 168, Omarama 204, Palmerston 164, Dunedin Aero 124, Dunedin 126, Oamaru 186, Queenstown 189, Alexandra 198, Invercargill 136, Raoul Is 88 {record low}, Campbell Is 62, Chatham Is 135]
