A dying southwest airflow and some ridging lead to a cooler than normal night tonight for the North Island. The South Island is starting to change however as a northwesterly airflow starts to build, coastal areas are still fairly average but inland especially the further south you go will see slightly warmer than average overnight lows.

A northwesterly airflow brings a warmer than normal day for most of the country on Saturday especially in the east, day time highs may actually reach into the late twenties despite some of the mid twenty degree highs listed below. In the west especially right on the coast temperatures are average due to onshore winds.
