We have the full forecast right up to Queen’s Birthday Monday and it includes the big southerly blast about to hit the country.

The southerly arrives in the Deep South on Thursday morning and slowly moves northwards across Thursday and Friday.

By Friday night the main southerly change moves over the North Island meaning Saturday will be colder than average in most parts of New Zealand.

Sunday, however, does see drier weather in many regions (showers in the east) and Queen’s Birthday Monday looks warmer with westerlies and sunnier in the east (but a few showers in the west again).
