NZ weather summary January 1957
« on: May 02, 2018, 03:11:56 PM »
January 1957: It was unusually dry and sunny. The long spell of settled weather was welcomed by holiday-makers and farmers alike. Shearing and haymaking were in full swing after numerous setbacks in previous months. Fruit ripened quickly and was harvested under excellent conditions. By the end of the month however, pastures were drying up and this was adversely affecting dairy production.

[In the weather sequence, pressures remained high from the 7th to the 26th, especially over the North Island, though a tropical cyclone formed near New Caledonia a week earlier passed east of East Cape between the 11th and 13th, bringing some rain to Gisborne and Hawkes Bay and unusually heavy seas from Tauranga to Napier. Depressions far to the south of the country brought less settled conditions to the far south and the southwest.]

Rainfall: Rainfall was less than a quarter of the normal value over most of the Auckland province, also over the greater part of Taranaki and Marlborough. The greatest deficiency was in Northland, where few stations received even 0.5”. Only in Otago and Southland did totals reach the average value. Thunderstorms affected parts of Southland and Canterbury on the 6th. In the Methven district of inland Canterbury there was also heavy hail, which caused serious crop damage.

Temperatures: Temperatures were mainly above normal by about 1F. On the Canterbury coast and about Cook Strait it was warmer than usual by about 2F-3F. The highest maximum recorded was 96.0F (35.5C) at Ashburton on the 31st.

Sunshine:
Except in Otago and Southland, sunshine was well above normal, mainly by about 50 hours. For Auckland, Palmerston North, Nelson and Blenheim it was the sunniest January in 35-50 years of records. The highest total was 335 hours, at Blenheim.

 [For the North Island and northern third of the South Island, January 1957 is still the sunniest January overall for which a sufficient number of reliable records exist. The following stations also set records for January: Kaitaia (315), Kerikeri (314), Masterton (306), Ohakea (323), Foxton (329), Wanganui (303), Hanmer (294) and Christchurch (288). The 335 is also the equal-highest NZ total for any month, also recorded at Taupo in January 1950. {PS – 335 exceeded in the electronic era, but a manual reading would almost certainly not have done so.}]

[Some totals: Te Hapua 273, Kaitaia 315, Kerikeri 314, Whangarei 299, Auckland 316, Tauranga 313, Whakatane 297, Taupo 301, Hamilton 298, New Plymouth 309, Masterton 306, Gisborne 288, Napier 301, Paraparaumu 284, Ohakea 323, Palmerston Nth 302, Levin 284, Wellington 300, Wanganui 303, Westport 276, Hokitika 230, Greymouth 221, Haast 173, Nelson 326, Blenheim 335, Grassmere 307, Mt Cook 170, Methven 279, Christchurch 288, Tekapo 261, Timaru 233, Waimate 217, Omarama 227, Dunedin 204, Queenstown 240, Alexandra 232, Invercargill 197, Campbell Is 96, Chatham Is 262 (new station – its January LTA was only 186)].
