“You’re looking at daytime highs of 26C on Saturday, 25C on Sunday, and 24C on Monday.”
Overnight lows are expected to be 15C on Saturday and Sunday.
Corrigan said the average January daytime high in Whanganui was 22.1C, so temperatures were still “a touch above average”.
Sunshine is expected to be most prevalent on Sunday morning.
“There will be clouds around on Saturday afternoon and then thin, higher-level clouds coming across before the rain arrives on Sunday”, he said.
“It‘s still going to be quite bright in the middle of our sandwich.”
Northwesterly winds would pick up on Saturday afternoon before dying down on Sunday, Corrigan said.
