Tuesday’s national forecast – A southerly gale and North Island rain (+9 Maps)

Welcome to the first day of summer on the meteorological calendar! A low will today lie over the eastern upper North Island and behind it comes a strong to gale force southerly through Cook Strait, Taranaki and up across parts of the North Island. Auckland may have strong to gale force winds forming for a time today.

Rain and showers will also impact the North Island, mostly on the eastern side up to about Gisborne.

The South Island, however, is much more settled with growing high pressure although that southerly may be windy from Canterbury to Marlborough, especially in exposed coastal areas with gales around Marlborough for a time before easing.

It will be a cold start for inland parts of the South Island too – but a fairly mild day ahead.

The eastern North Island will be several degrees colder than average with some parts of Hawke’s Bay experience daytime highs only 1 degree above the overnight lows! The West Coast over in the South Island, on the other hand, is warmer than normal.

Seas will also be dangerous from Taranaki to west Auckland to western Northland. Big waves and gales combined means it’s not a day to go fishing on the rocks or out on a boat.

Here are the regional forecasts for Tuesday… As always, for highly local details please refer to the HOURLY forecasts at both and
