“The water up there is also already quite a bit above average temperature, so all that does is increase that amount of moisture that’s dragging down, bringing that very sticky, muggy feeling to upper parts of the North Island.”
The hot air mass was also affecting the weather in Wellington, but not to the same degree.
MetService said the hot and sticky weather could become worse tomorrow.
“On Saturday, it might push off for a little bit of respite, but it is not long-lasting respite.
MetService said the very warm, humid air is likely to return on Sunday and could linger until Tuesday.
Some wet weather could also be thrown into the mix tomorrow but there was a stronger chance of rain around Auckland on Sunday and early next week.
“Wet weather will be coming and going, so it’s not going to be raining every day, all day, but there will be some rainy days as we make our way through the weekend and next week.”
MetService also advised that humidity would typically be at its peak around dawn.
