October 1963: It was exceptionally dry, and also rather warm. Barometers were high during the month and there was much less wind than usual. Pasture growth was somewhat retarded, and some crops were badly in need of rain, though there was some relief from light falls near the end of the month.
Rainfall: Very few places in the North Island and the northern half of the South Island had even half the average rainfall; but in Otago and Southland rainfall was mainly about average. Some areas received less than 10% of average, notably the Kaitaia-Dargaville area; east of Lake Taupo, parts of South Taranaki; Wellington and parts of southern Wairarapa; northwest Nelson; and Nelson city and the area to the east. There has not been a drier October in
Wellington in 102 years of record; and in Nelson in 81 years of record; and for a number of other stations it was also the driest October on record.
Temperatures: Temperatures were mainly about 2F above average, highest departures being in inland and some eastern parts of the South Island and in central districts of the North Island. There was snow to low levels in Southland on the 13th, with some lamb losses.
Sunshine: Most of the country received a little more than average sunshine. Nelson and inland districts of the South Island together with the Gisborne-Taupo area were especially favoured, with surpluses of more than 20 hours. In Wanganui-Manawatu, Westland and coastal South Canterbury totals were somewhat below average.
