A west to northwesterly airflow lies across New Zealand today moving around a large anticyclone to the north.
Expect mostly sunny weather for the upper North Island, perhaps some early fog to start then again overnight. Winds are light tending onshore in the afternoon. Mostly sunny about the lower western North Island also, perhaps some morning cloud then clearing away, winds build from the west or northwest. The east coast has a sunny and hot day, northwesterlies for most, tending northeast in the afternoon about coastal Hawkes Bay and perhaps Gisborne. Morning low level cloud about Wellington breaks to sun and some high cloud, winds gusty from the north.
Mostly cloudy for the West Coast south of about Hokitika with showers, turning to rain for Fiordland at night with heavy falls. North of Greymouth skies are sunnier with some high cloud, the odd shower sneaks northwards through to about Westport in the evening however. Mostly sunny about Nelson and Marlborough, a touch of high cloud and afternoon north to northwesterly winds. High cloud for Canterbury through to Southland (sun may break through at times), expect gusty northwesterlies especially in the afternoon / about inland areas. Around midnight a southwest change pushes into Southland bringing rain, moving into Otago overnight.
Max temperatures – Expect highs to reach into the mid 20’s for the South Island’s east coast, perhaps even late 20’s for the North Island’s east coast.
