Through December 24 and 25 people can expect “quite-light to fresh” north-westerly winds, moving southerly into Boxing Day.
“The only time we’re expecting a change is from the 26th where the winds change to a southerly as the front that was over the North Island moves over to the east with the southerlies behind it,” Shiviti said.
“We’re expecting the showers to be most significant on Boxing Day.”
On Friday showers can once again be expected in the morning, easing in the early afternoon.
Thursday and Friday’s temperatures, and into the weekend, should remain a consistent high of 21C and overnight lows of 14C.
