Humidity set to roll back in on Sunday

Now is the time to catch up on your sleep with Auckland set to return to hot, sleepless nights as soon as Sunday.

Weatherwatch's Philip Duncan said the break in humidity was partly thanks to Cyclone Gita pulling in a southwesterly change.

But a sub-tropical northerly developing over New Zealand on Sunday would see the humidity jump back up for a couple of days.

Duncan said the short-lived spell would not be as "strong and powerful" as the unrelenting humidity Auckland had already experienced this year.

"It's probably not going to be quite as brutal," Duncan said.

"There will still be people saying 'gosh it's hard to sleep'."

The humidity would be felt particularly up north and in Auckland it was expected to be back in the 90 per cent range, he said.

According to MetService at 1pm today the humidity in central Auckland was 71 per cent.

MetService meteorologist Hannah Moes said that generally the weather was easing across the country.

"The southwesterlies are the reason it feels more comfortable today," she said.

"It's brought a cooler, drier, air mass across New Zealand."

Prior to the change Auckland had been stuck under a muggy, humid, air mass and it was "unusual" that it had hung around for so long.

It should stay cool and fine over the weekend with a high of 25C on both days.

But with the southwesterly set on move on late Sunday it would become warmer.
