NZ season update

The east stays dry and
the lower North Island is wet. June is still warm and cloudy in the
north but the second half of July brings high rainfall with flooding to
northern half of North Island and northern South Island, and dry
conditions for the far south. Because of lateness of lasting snow NI
skiers may have to wait until mid-August for their season to open.
August - In the second half it is still dry in the east but wet, warm
and cloudy in the north. Over much of the South Island, winter cold will
often accompanied by sunshine.
September - sunny and continuing dry in the east and north of the North Island but wet in south of the South Island.
October - a very wet month for the SI.

west, but cooler conditions in many parts of the east.
December - in the second half, agricultural drought is back in full swing, expected to affect the North Island and Canterbury.
