NZ weather summary May 1958
« on: May 05, 2018, 08:21:59 PM »
May 1958:  A stormy month, cloudy in most places. In the North Island the absence of cold spells was favourable for growth. In Southland however, the persistently wet conditions affected stock health. Many gales were reported during the month, especially about Cook Strait and in western and southern districts of the South Island. The worst gales from a westerly quarter in these districts were on the 5th and 6th, and from the 28th to the 31st; on the 31st a particularly violent storm caused extensive damage in Southland. Southeasterly gales affected most of the North Island on the 11th. Small tornadoes were reported on the 6th near Levin, and on the 28th in 3 West Coast regions.

Rainfall: In the South Island high country, the West Coast and western Southland, rainfall was from 2 to 4 times the normal value, and for a considerable part of this area it was the wettest May on record. Otira recorded 57.65”. Taranaki, the King Country and most of the Wellington province also received more rain than usual. The only areas appreciably drier than average were most of northern Northland and the North Otago coast. Heavy rain in the Wellington province from the 10th to the 12th in a spell of southeasterly winds caused flooding in parts of the Wairarapa and also in the Oroua, a tributary of the Manawatu River.

Temperatures:
Temperatures were 2F-4F warmer than usual in eastern districts from North Canterbury to Gisborne. Elsewhere they were close to normal. Snow fell to low levels in parts of Canterbury on the 9th.

Sunshine: Most districts had about 30 hours less sunshine than usual. New Plymouth’s 82 hours was its lowest in over 40 years of record. On the coast from Invercargill to Gisborne and in the far north sunshine was about average.

[Some totals: Te Hapua 146, Kaitaia 138, Kerikeri 132, Whangarei 120, Auckland 112, Tauranga 145, Whakatane 166, Taupo 116, Hamilton 100, New Plymouth 82, Masterton 108, Gisborne 163, Napier 149, Paraparaumu 108, Ohakea 108, Palmerston Nth 94, Levin 83, Wellington 90, Wanganui 108, Westport 77,  Hokitika 103, Greymouth 78, Haast 92, Nelson 134, Blenheim 163, Grassmere 148, Mt Cook 74, Methven 137, Christchurch 133, Tekapo 101, Timaru 136, Waimate 128, Omarama 139, Dunedin 104, Queenstown 75, Alexandra 98, Invercargill 101, Raoul Is 201, Campbell Is 16, Chatham Is 65].
