NZ weather summary November 1977
« on: February 15, 2012, 06:57:16 AM »
November 1977:   Pressures were higher than normal over New Zealand, with a predominance of winds from a westerly quarter. Over most of the country this was a cool, dry, sunny month, with occasional spells of warm fine weather. Many North Island farmers reported good grass growth and stock in good condition, but in many parts of the South Island grass growth was poor. In some areas berry fruit was not ripening as well as could be expected at this time of year. On the 9th a fishing boat was stranded on rocks near North Cape during a period of gale force winds.

Rainfall:
The only areas with above normal rainfall for the month were parts of Waikato, Taranaki, Manawatu, Wellington and Marlborough. The largest departures above normal were in the Wellington region, where nearly half the month’s rainfall fell from the 20th to 22nd. At Kelburn over 40mm was recorded in 6 hours on the 20th, and at Taita nearly 50mm fell in 6 hours on the 22nd, and more than 70mm in 12 hours on the 21st/22nd. Roads and railway lines were blocked by land slips and floodwaters at Petone and Porirua, and some houses in the Hutt Valley were evacuated. At Cape Reinga more than 80mm was recorded in the 48 hours to 9am on the 10th. Areas with rainfall appreciably below normal were Poverty Bay, Hawkes Bay, parts of Wairarapa, Nelson and the east coast of the South Island.

Some monthly totals (mm): Cape Reinga 106, Kelburn 177, Stratford 207, Rai Valley 175, Cape Campbell 62; Thames 40, Rotorua 52, Waipukurau 36, Napier Aero 29, Balmoral Forest 15, Christchurch 27, Earnscleugh 19.

Temperatures:
  Temperatures were below normal throughout New Zealand, in many areas of the North Island by more than 1.0C, and in the South Island by at least 0.5C. The coldest spell occurred during the first 3 days of the month with maximum temperatures well below normal; the longest warm spell was from the 19th to 22nd.

31.0C
maximum at Eyrewell Forest on the 25th, -4.0C minimum at Naseby on the 2nd.

Sunshine:  Most areas had sunshine hours near or above normal for the month, many places being above by 25 to 35 hours. At Christchurch Airport the total of more than 250 hours was about 20% above normal. Parts of Auckland, Westland and Southland were slightly below normal.
