Your Christmas day weather report

Don't fret - the heavy rain soaking the North Island overnight will not stick around for Christmas.

Most of the country should have a relatively fine Christmas day, with only a few isolated showers mainly confined to the west of both islands.

The front mainly affecting the North Island and which caused heavy rain overnight should ease today, said MetService meteorologist Ciaran Doolin.

The front would continue to move east over the morning, possibly bringing more showers to Gisborne, Bay of Plenty and the Coromandel, but it was clear of Northland, Auckland and western Waikato.

The front should clear later today but will be followed by showers, which could be heavy and thundery in the northern South Island and central North Island, Doolin said.

In the South Island, inland areas like Canterbury were the only places likely to be clear, but the east, west and south coasts can all expect showers.

Looking to the weekend, things should be drier for Christmas, Doolin said.

"This southwesterly flow over the country is easing into Christmas Day.

"Overnight tonight and into tomorrow the winds are likely to be a bit stronger, the showers are likely to continue in some places but as we go into Saturday and Sunday those showers are likely to become isolated to the west of the

 Winds are likely to ease as well, he said.

'There may be a bit of rain around on Christmas Day, but it will be isolated and contained to west of both islands."

A few heavier showers are likely in the deep south, but in holiday hotspots like Nelson, the Coromandel and Mt Maunganui the day was generally shaping up to be fine.
