MetService warns of 3m swells for parts of NZ

Kiwis on the west coast of New Zealand are being warned about “higher-energy waves” over the coming days. 

MetService said there are “very long period swells” in the forecast, which could be up to 18 seconds long.  

This will result in the waves reaching high up the beach and could be between 2 to 3 metres in height, MetService said. 

“So take extra care about the coast.”

Sunday is shaping as being a fine and sunny day for most places around the country but a southerly flow over the North Island on Monday will bring rain or showers to Gisborne and northern Hawke’s Bay. 

The South Island is also in the firing line with rain for parts of the island. 

“A west to southwest flow covers the South Island, with a weak embedded front expected to bring brief rain to the south of the Island,” MetService said on its website. 

“On Tuesday, a southerly flow continues to affect the North Island, while a ridge builds across the South Island. The high weakens over the South Island on Wednesday as a front embedded within a strong north to northwest flow moves onto Fiordland.” 

MetService said on its website that the front is expected to bring rain to the west and south of the South Island.

“There is low confidence that a heavy rain warning will be required for Fiordland and the far south of Westland on Wednesday and early Thursday,” MetService said. 

It comes after a fine and sunny day for most of New Zealand on Saturday but one place needed the blankets all day. 

Many Kiwis in the South Island woke to a white blanket of frost as temperatures plummeted into the negatives. 

Down in Central Otago, Lauder residents woke to a numbing temperature of -6.6C, according to NIWA.

And it barely warmed up throughout the day, with NIWA saying it was a “cold and dreary day”, with a temperature of -3C at 2pm.
