Today sees a southerly airflow cover most of New Zealand, although it’s relatively weak. Some cloud and the odd shower in the east from Banks Peninsula northwards (more so near the coast), and heavy frosts morning and night inland for the South Island. A few showers on Tuesday about the east and north of the North Island. Dry in the west from Waikato southwards, and the South Island has a ridge of high pressure. A similar pattern continues on Wednesday.

White – Heavy frosts to start the day for the inner South Island; watch for potential black ice on the roads. The inner North Island, while also having a frosty start, will likely not be as cold.

White – Heavy frosts once again for the South Island, a little more widespread this time. Once again, while the inner North Island will be frosty, it may not be as cold as the inner South Island.

Blue – A low pressure system moving from west to east over northern Northland during the day brings a spell of rain for Northland which may be heavy, especially in the east.

Purple – Gusty southeasterly winds are also likely but at this stage, winds are not looking to be a gale but they may gust close to gale at times in exposed coastal areas.

White – Another frosty start for the inner South Island, however not as cold as the past few days. The inner North Island may only just dip down to 0 around dawn.

Blue – Tuesday’s low hasn’t moved much and may bring some heavy rain to northern parts of Auckland / Northland during the day.

Purple – Winds remain gusty from the southeast.
