Thick winter fog rolled across Auckland before dawn on Wednesday and grounded a run of regional flights, leaving early travellers stuck in terminals while the murk slowly burned off. Fog restrictions were imposed at Auckland Airport at 4.36am, and by mid-morning the low cloud had cancelled or held up more than a dozen services heading out to smaller centres around the North Island and the top of the South.
The disruption fell almost entirely on regional flights. By 6.50am, seven flights had been cancelled and 12 delayed, according to figures reported by the New Zealand Herald. Passengers booked to WhangΔrei, Kerikeri, Tauranga, Rotorua, Gisborne, Napier, New Plymouth, Palmerston North, Nelson and Blenheim were the ones checking the departure boards and waiting for news, with some delays stretching out to about three hours.
Flights to the main centres kept moving. Services to Wellington, Christchurch, Dunedin and Queenstown ran as normal, and international departures were not affected. That split is the usual pattern when fog settles over Auckland. The larger jets that fly the busy trunk routes and overseas services are able to keep operating in poorer visibility, while the smaller turboprop aircraft that do most of the regional work are the first to be held on the ground and the last to get moving again once conditions improve.
Visibility was the problem. At 6.30am the airport was reporting visibility of about 400 metres, and on the Northwestern Motorway it dropped as low as 100 metres, turning the morning commute into a slow crawl for drivers as well. The fog was not confined to the airport either. Much of the North Island woke to a misty, murky start, with low cloud sitting over towns and motorways well beyond Auckland.
MetService meteorologist John Law said the conditions were textbook for a foggy morning, pointing to “moist air, cold temperatures and light winds creating perfect conditions for a foggy start”. That combination is what produces radiation fog, the type that forms overnight when clear skies let the ground cool quickly and calm air lets a shallow layer of moisture condense close to the surface. It is the classic winter set-up for Auckland, and it tends to clear only once the sun climbs high enough and the wind picks up enough to mix the cold layer away.
That is exactly how Wednesday played out. The fog was forecast to break between 8am and 9am as temperatures rose and the breeze freshened, and the airport confirmed the restrictions were lifted mid-morning after roughly five hours in place. By around 9am the running tally had eased back, with RNZ reporting five regional flights cancelled and 12 delayed as the backlog began to unwind and aircraft returned to their schedules.
For the travellers caught in it, a cancelled early flight can knock out a whole day. Regional routes often run only a handful of times a day, so missing the first departure can mean a long wait for the next available seat, a scramble to rebook connecting travel, or a rental car and a long drive instead. Business travellers heading to meetings, patients travelling to appointments and families trying to get away all felt the same squeeze while the fog held.
Auckland Airport and airline staff were on hand through the terminal to help passengers and pass on the latest information as the situation shifted through the morning. Anyone flying regionally on a still, cold winter morning is generally advised to check their flight status before leaving home, since fog can form and lift quickly and the picture can change hour by hour.
None of this is new for Auckland. Winter fog is a recurring headache at the airport, and cold, calm mornings through June, July and August regularly bring the same story of grounded regional flights and delayed departures. The airport sits on low, flat land beside the Manukau Harbour, and the mix of moisture and still overnight air that gathers there is well suited to forming fog when the weather turns clear and cold. Because the fog usually clears within a few hours of sunrise, most of the disruption is concentrated in the early morning, exactly when a lot of the regional network is trying to get its first flights away.
Wednesday’s episode was a relatively short one by winter standards, with the worst of it over by late morning and flights back on track before lunchtime. Even so, it was another reminder that the smaller centres at the ends of the regional network carry much of the cost when the weather closes in over the country’s biggest airport, and that a quiet, foggy start can ripple out across the map long before most of Auckland has finished its morning coffee.
