Rainfall

July was a dry month for most parts of the country with the central North Island, Bay of Plenty, eastern Nelson-Marlborough and Canterbury regions experiencing well below normal rainfall (<50%).
Below normal rainfall (50-79%) characterised much ofAuckland, the south-eastern coast of the North Island and the western coast of theSouth Island.
In contrast to this general dryness, significant rainfall events occurred in Northland and south-west Southland. These events contributed to the well above normal (> 149%) rainfall anomalies recorded in the regions during July.

A pocket of below average (-1.20 to -0.51°C) mean temperature wasrecorded in the districts of Waitomo and Ruapehu, while above average temperatures(0.51 to 1.20°C) were observed in southern Canterbury and Otago.
A mid-winter warm spell hit the eastern South Island and some areas of the North Island on the last day of July setting new maximum daily temperature records at several locations.

It was an unusually sunny mid-winter with the Waikato and Bay of Plenty experiencing well above normal (>125%) sunshine hours.
The high levels of sunshine extended to the rest of the North Island, despite the high rainfall in Northland, as well as to the north-west of the South Island where above average sunshine was recorded (100-125%).
