For the South Island above normal rainfall fell in the Tasman Region, Nelson, Marlborough and South Canterbury. Below normal rainfall was recorded in the south west of the South Island, east coast Southland and the Otago Peninsula. Normal rainfall fell elsewhere.
Predicted air temperature: Air temperatures are likely to be near average or above average in all regions for the season as a whole.

The North Island experienced below normal temperatures in Northland, the Waikato Region and coastal Taranaki. Normal temperatures were observed elsewhere.
