In this case, for Auckland the forecast is for really fine days with fog at night when it gets cold, she said.
Aucklanders have woken to a stunning sunrise as another fine and warm day is forecast.
The skies turned from scarlet to a blazing orange over the nation's biggest city this morning, as the sun's rays lit up the clouds ahead of a fine day with an expected top of 20C.
The delightful weather and temperatures into the low 20Cs are expected to last into Friday, when some late showers will signal the start of a wet weekend.
According to WeatherWatch.co.nz, the warmer than average week ahead could end by the time the weekend rolls around, when potentially a sub-tropical rainmaker is expected, followed by a cooler southerly.
"Some long-range data does suggest a large Tasman Sea low may affect New Zealand, perhaps next weekend, as certainly energy is building out west over the coming week for a low and rainmaker to grow," WeatherWatch said.
WeatherWatch.co.nz also warned of fog throughout inland areas over the next several days, especially over the North Island - this could disrupt more flights.
Fog can sometimes be tricky to forecast so be prepared for possible "sudden fog", the forecaster said.
Elsewhere, today's fine weather and temperatures into the low 20Cs should reach from Northland and Hamilton to the Coromandel, down through the Bay of Plenty to Napier.
Wellington can expect sunny spells and a top of 17C, while New Plymouth is tipped to hit a high of 19C.
In the South Island, Christchurch and Dunedin can expect cloudy skies with tops of 16C.
Greymouth on the West Coast is expecting a bright and sunny 19C, while Queenstown is also tipped to bathe under blue skies and a high of 16C.
