Wednesday's national forecast

Today is the day our Tasman high becomes a Pacific high.

As the high moves across the country, shower chances will shift from the South Island’s West Coast, Southland and Otago regions this morning to the North Island’s Hawkes Bay and Gisborne regions for tonight.

Tuesday's national forecast

As high pressure continues to move in off the Tasman, New Zealand is looking at another quiet weather day.

Not everyone will see bright sunshine, however.  But the chances for rain will be few.

Tropical trouble brewing

The tropics have been somewhat quiet this year - especially when compared to the dramatic cyclone season last year.  However activity is about to step up with three zones showing signs of life.

Tasman high could mean a quiet week ahead

Get ready for a quiet weather week.

As March comes to an end, it looks like we will be in for some very dry and settled weather.  A large ridge of high pressure will very slowly slide over New Zealand.

Monday's national forecast

High pressure will build in off the Tasman today.  That will mean dry and settled weather for most of the country.

Saturday's national forecast

Filed in:

Most of New Zealand is looking at a dry and settled Saturday.  However, rain is on its way and by late tonight much of the country should be getting wet.  That’s because a long area of low pressure will be unsettling our weather very gradually today.

Friday's national forecast

A trough of low pressure will slide west to east across New Zealand today.

A 2 C rise in temperature could put large parts of New Zealand under water

Sea levels will rise up to 22 metres even if the worst scenarios for global warming are avoided, researchers say.

An international team of scientists, which included a New Zealander, found that a 2C increase in global temperature would still cause the world's oceans to rise between 12m and 22m.

Weekend outlook

For those of you hoping for a dry weekend, I wish I had better news for you.

But it appears that a couple of weather systems will combine forces to make this a pretty wet weekend for most of New Zealand.

Did you escape the latest low?

Filed in:

Some Kiwis actually managed to get through the last few days with very few effects from the pair of sub-tropical lows that have moved through this week.

Our latest low is continuing to die as it moves to the south.  That means things will still be a little unsettled today.  But any the threat for heavy rain and strong winds is pretty much over.
