Makgabutlane said it would also remain warm overnight.
“Those minimum temperatures will be in the high teens, and around 18C to start Christmas morning off.”
Daytime highs will be 26C on Saturday, 27C on Sunday and 26C on Monday.
Saturday would be mostly rain-free but inland showers could drift onto the coast on Sunday, Makgabutlane said.
She said those showers could also pass through Whanganui city on Christmas Day.
Clouds will linger on Boxing Day.
“The wettest of the weather should have moved through, though.
“It’s a very similar story in terms of temperatures, with 25C expected.”
