It’s a foggy start this morning across the upper North Island with flights now being impacted. WeatherWatch.co.nz forecast the foggy conditions due to centre of high pressure crossing the country overnight and bringing light winds a slightly more humid airflow.

Fog may linger until mid to late morning in some places due to today’s set up. Once fog clears it will be mostly sunny.

As of 7am several flights in and out of Auckland domestic airport were either cancelled or delayed.

Foggy conditions are most likely when the centre of a high pressure system is either directly over New Zealand or moving out to our east, which is the set up today and perhaps a number of days next week too. Long cool nights and warm afternoons also help make fog.
