Most regions across New Zealand are warmer than normal today thanks to sub-tropical winds over the North Island and west to north west winds over much of the South Island.

NORTH ISLAND:
An area of rain and showers moves into Taranaki and the south west corner of the North Island down to Wellington and even Wairarapa later. Mainly dry in the morning though. North of Taupo and Wairarapa most places look dry with just a few showers in the west up to about Waikato. Sub-tropical northerlies for many places.
Highs: 17 to 26 (likely warmest in Hawke’s Bay)

SOUTH ISLAND:
Rain is mostly confined to the southern half of the West Coast today and becomes heavy. Showers in Hokitika and maybe Greymouth but could be sunny at times in Westport and dry. A couple of showers around coastal Southland and coastal Otago otherwise dry across the rest of the South Island with sunniest weather in Canterbury. Rain in Cook Strait might brush Nelson and the Marlborough Sounds, otherwise dry there. Variable winds but mainly from the northerly quarter across the island.
Highs: 12 to 23 (coolest in Queenstown)
