Overall, winter temperatures were near average (-0.50Â°C to +0.50Â°C) across most of the country.
There were pockets of below average temperatures (-1.20Â°C to -0.51Â°C) in western Waikato, Tararua, Wairarapa, mid-Canterbury, Tasman and coastal Otago.
Pockets of above average temperatures (+0.51Â°C to +1.20Â°C) were also present in Christchurch, central Otago and the Manawatu.
The nation-wide average temperature in winter 2015 was 8.4Â°C (equal to the 1981-2010 winter average, using NIWA’s seven-station temperature series which begins in 1909).
However, this average picture of winter temperatures does not convey the nature of the extremely low temperatures that affected the Mackenzie Country and Central Otago in late June.
These temperatures were some of the lowest ever recorded in New Zealand and will make winter 2015 one to remember.
Rainfall was below normal (50-79%) or well below normal (< 50%) for some eastern areas of New Zealand including Northland, Bay of Plenty, Gisborne, Hawke’s Bay, Wairarapa and north Canterbury.
Rainfall was either above normal (120-149%) or well above normal (> 149%) for southwestern and western parts of both the North and South Islands and coastal Otago.
As of 1 September 2015, soil moisture levels were below normal for this time of year for Hawke’s Bay, coastal Wairarapa, eastern parts of Canterbury and North Otago.
Winter sunshine was near normal for most of the country (90-109%). Above normal (110-125%) sunshine was observed in western Waikato and Marlborough and below normal sunshine (75-89%) was observed in Taranaki.

Not sure how the BOP can be drier than normal, we have mud up to our eyeballs after the wettest winter in a long time in Tauranga!

It is all realative. Maybe it is always really wet there and just a little drier this winter (but still quite wet). I know that Auckland can have a ‘very dry’ month, and that same rainfall would be a ‘wet’ month in Christchurch.
