Weather: Fog blankets Wellington in start to 'mostly tranquil' week

Wellington has woken up to a thick blanket of fog on Monday, with the nation's capital covered in a woolly white layer earlier in the morning.

An image from MetService's Kelburn office shows the fog stretching across the city and harbour.

"Unlike the cloud that was streaming down Ngaio gorge last week, this cloud was lying through Thorndon, across the city, and stretching back towards Newtown," MetService's Facebook post reads.

"Pan around the picture to see the extent of the cloud."

The heavy blanket was kicked off as the sun rose, with a timelapse showing the fog clearing away between 7am and 8:30am.

'Mostly tranquil' week ahead

NIWA says with high-pressure overhead, it's shaping up to be a "mostly tranquil" week across New Zealand.

"A few isolated showers will remain possible in the east and top of the North Island, but amounts will be light," it says on Facebook.

It's hopeful that some "meaningful rain" could arrive later this month and give a hand to places facing record-dry conditions.
