A northwesterly airflow lies over New Zealand on Monday, a few weak frontal zones sit over the North Island while a stronger front affects the far south.

For the western North Island expect cloudy areas and occasional sun, a few showers possible also but many dry spells. During the afternoon showers become a little more organised with some perhaps even becoming heavy. A thunderstorm risk is also present about the Waikato and inland Bay Of Plenty. Apart from the risk of a morning shower Palmerston North southwards is mainly dry. Along the east coast expect sunny areas and increasing high cloud with northwesterlies, there may be a shower late afternoon / evening especially in the ranges.

Temperatures in the low to mid twenties, high twenties along the east coast for a time.

The West Coast of the South Island has mostly cloudy skies, perhaps a shower or two about. Fiordland sees rain for much of the day with the odd heavy fall. Winds from the northwest. Nelson, Marlborough and Canterbury have mainly sunny and hot conditions with north to northwesterly winds. Rain for Southland which starts to creep a little further north into Otago during the afternoon, parts of northern Otago may stay fairly dry however.

High’s in the mid to high twenties from Nelson through to Canterbury, perhaps early thirties in some isolated spots along the east coast. Temperatures may reach into the twenties about Buller then further south and right around to Southland high’s are in the mid teens. Mid to high teen temperatures for southern Otago, low to mid twenties for northern Otago.
