« on: March 23, 2012, 06:31:01 PM »
September 1973: September was warmer than usual, and mainly favourable for farming, though sunshine was below desired levels in the North Island, while parts of Canterbury were still too dry.

Rainfall:
In the North Island rainfall was mainly above normal. In Coromandel and parts of Bay of Plenty and central Hawkes Bay it was more than double the normal value. The heaviest rain over the North Island was from the 16th to the 18th, with flooding in Ohura, King Country. In the South Island rainfall was mainly below normal. Over the greater part of Canterbury with parts of Marlborough and Otago it was less than half the average.

327mm
at Te Puke; 8mm at Tara Hills, Omarama. Campbell Island managed 30 days of measurable rainfall, though one of these had only 0.1mm.

Temperatures:  Temperatures were above normal, mainly by 1C to 1.5C. The warmest period was the last 5 days of the month; and the coldest period was from the 6th to the 9th, with snow on the ranges and parts of the South Island high country.

28.8C maximum on the 30th at Ashburton and Waipara.

Sunshine: 
Sunshine was 20-60 hours below normal in northern and some western districts of the North Island and about Wellington, with particularly low values in the Rotorua-Taupo area. Elsewhere it was mainly about normal, but parts of the West Coast with the Alps and the Southern Lakes district were favoured with about 20 hours above normal.
