After a chilly start to the week MetService has forecast cloudy weather and an average temperature of 13C to 14C throughout the week.
Meteorologist Sarah Haddon said yesterday's cold weather was caused by a ridge over central New Zealand that was directing a southerly flow over the eastern part of the North Island.
"There's currently an onshore flow in the Bay with some showers and cloud mostly affecting the east coast of the North Island."
But Ms Haddon said the region could expect an "improving trend" over the coming days as the ridge moved to an "offshore flow" by tomorrow. It was forecast that as today progressed the ridge would slowly move and allow some cloud to clear.
"The cloud should break up today so the sun should be able to get through and warm things up too," Ms Haddon said.
