NZ weather summary December 1955
« on: April 29, 2018, 10:17:10 AM »
December 1955: A warm month. An unusual predominance of high barometric pressures was associated with dry, settled weather in central and southern districts. Over most of the South Island pastures were drying up and rain was badly needed. For Northland it was an exceptionally dull and wet December. Flooding was reported over large areas between Dargaville and Kaikohe on the 6th and again in parts of Northland on the 17th and 18th.

Rainfall: Rainfall was less than half of average over the South Island, except in Nelson and Marlborough and parts of the West Coast. In Central and North Otago it was the driest December on record; a few stations reported no rain at all. For most of Northland rainfall was more than double the usual amount. Whangarei (at Glenbervie Forest) had 10.84”, about 3 times the average. Over the remainder of the country rainfall was close to or slightly below normal.

Temperatures:
Temperatures were above normal over the whole country, and the departure exceeded 2F over almost all of the South island south of Kaikoura and Westport, and also over the Auckland province. In Central and West Otago it was the warmest December since 1935 (departures up to 6F).

An unusually cold spell affected most of the country from about the 26th to the 28th. Snow was reported on the ranges of the South Island down to 3000 ft, and in some inland districts as far north as Canterbury damage to vegetables from sharp frosts was recorded.

[Any suggestion of a return to near-average temperatures after this was put paid to by the exceptional warmth of January 1956.]

Sunshine: Sunshine was above normal over most of the South Island, also in Wellington and Taranaki provinces. Departures exceeded 60 hours in Otago, with 305 hours at Queenstown. It was cloudier than usual over most of the Auckland province and also in Hawkes Bay. In Northland it was exceptionally dull, with departures of 60 to 110 hours. Whangarei (Glenbervie) recorded only 113 hours.

[Some totals: Te Hapua 152, Kaitaia 159, Kerikeri 135, Whangarei 113, Auckland 235, Tauranga 233, Taupo 225, Hamilton 228, New Plymouth 271, Masterton 243, Gisborne 222, Napier 223, Paraparaumu 259, Ohakea 278, Palmerston Nth 250, Levin 243, Wellington 247, Wanganui 279, Westport 207, Hokitika 195, Greymouth 191, Haast 195, Nelson 248, Blenheim 232, Grassmere 226, Mt Cook 230, Methven 248, Christchurch 234, Tekapo 298, Timaru 222, Waimate 198, Omarama 282, Dunedin 231, Queenstown 305, Alexandra 293, Invercargill 237, Campbell Is 104].
