“If you’re not enjoying the humidity, unfortunately it’s not really changing.”
Temperatures overnight are sitting at between 16C to 18C during the week.
Generally, the weather will bring “pretty muggy conditions” and continued high humidity, O’Connor said.
Drier and sunnier conditions are anticipated for Tuesday, but on Wednesday showers are returning. The rainfall will be less heavy than Monday’s showers.
“For most of the North Island, it will be a fairly wet week.”
Wellington Anniversary Day
Looking ahead to Wellington Anniversary weekend humid conditions are expected to continue with a chance of rain on Sunday.
There is a front approaching the West Coast of the South Island late on Friday, but how north that front travels will determine its influence on rain arriving in Whanganui for the long weekend.
“If you are outside in the heat make sure you’re prepared, and stay hydrated, use sunscreen and shade as needed.”
O’Connor said the ongoing warmth will be the most impactful part of the weather this week.
