Temperatures are anticipated to drop to an overnight low of 6C, with chilly nights ahead for Whanganui residents this week.
MetService meteorologist Mmathapelo Makgabutlane said a cold front would pass over the North Island and night-time temperatures were predicted to be in the single digits.
“If you can, get those winter blankets out a couple of days ahead.”
Monday’s weather is expected to produce mostly dry conditions, with maybe one or two passing showers.
Makgabutlane said Tuesday would probably be the wettest day, with multiple showers coming through in the afternoon, but the week’s rainfall was not expected to be significant.
