Westerly winds will persist throughout the day.
“For Christmas Day it’ll be certainly a bit windier about the coast,” Pawley said.
“Those westerly winds might be a bit fresh but further inland, it’ll be calmer.”
The winds may increase into Boxing Day, which is shaping as a day for indoor festivities or shopping.
A band of rain is projected to move northward, bringing showers throughout the day in Whanganui.
“You might see some fine spells once it’s gone through in the evening,” Pawley said.
“But there’s still the chance for showers about.”
Westerly and northwesterly winds will be most unsettled early in the day on Friday, and will ease into the evening.
The high on Boxing Day, Friday, is expected to be 23C with an overnight low of 12C.
