Cold front approaching lower South Island, get ready for a change (+Maps)

Some parts of the South Island are glorious right now with clear skies and fairly mild conditions – but the cold change is now approaching Southland.

As of early afternoon temperatures are mainly between 11 and 15 degrees which is mild especially under sunny skies. 

As you can see in the graph below (from our hourly Invercargill forecasts, as an example), the next few hours will see clouds roll in, rain falling and temperatures dropping.

Here are the 1pm weather observations from the lower South Island (click image below for live version)

The cold weather will be coming in surges. The first cold front (as of 1pm) was approaching Stewart Island and Southland – the next surge of polar air (the main event) will be later Friday and into Saturday.

The “computer generated’ data for the same period shows Dunedin faring worse. Surprised you didn’t look for the worst looking data for the south.

Hi there, we showed Invercargill as it gets the cold front before Dunedin.
