Sub-tropical airflows and northerlies are boosting NZ’s temperatures but following some rain through central NZ late this week, colder air will start to advance northwards.
By Monday a nationwide south to south west flow will move over New Zealand dropping temperatures.
For some in the north this will be especially noticeable at nighttime with overnight lows in places like Auckland dropping from 18C to 11C, while daytime highs in the south will drop with places like Christchurch going from a high of 18C to 20C on Sunday to just 13C by Monday.
In Australia – high pressure is the main feature, bringing a few showers to the south and east, otherwise dry inland with light winds.
The Tropics has some low pressure with Rarotonga most exposed to strong winds, heavy rain and bigger seas for a time over the coming several days.
