Fog affects Hamilton flights for second day

Early morning flights from Hamilton International Airport were cancelled this morning due to fog but flights are starting to resume as conditions improve.

Early mornings flights to Auckland, Wellington and Christchurch remained cancelled, but flights to both Auckland and Wellington were expected to take off from 10am.

Meanwhile, arrivals from all centres - except Christchurch - were showing as on schedule on the airport's website at 8am this morning.

In some parts of Waikato and South Auckland the fog has lingered for almost 36 hours.

WeatherWatch.co.nz head weather analyst Philip Duncan says the current weather conditions are all down to the wind.

"We need the breeze to move in and and clear this fog away - it failed to arrived yesterday in any widespread way across Auckland and Waikato which is why some areas never saw the fog lift".

Mr Duncan says the most recent forecast guidance data suggests the fog could linger again today in some areas.

"It's frustrating not being able to give an exact time, forecasters all around the globe battle with fog predictions - it is a very delicate balance as to when it forms and when it clears".

A south east breeze is predicted to move in but that Waikato and Auckland were currently being sheltered from this breeze.
