Indicators seem to be showing that the strong La Nina phase, most noticeable over the summer months, is continuing to wane.
Ocean temperatures across the tropical Pacific Ocean are about to approach their normal values for this time of the year after being above average for many months, particularly during our summer.
Climate models also suggest La Nina is weakening, with neutral conditions forecast throughout the southern hemisphere winter.
New Zealand appears to be heading for a normal winter with anticyclones delivering clear skies and frosty conditions interspersed with depressions and cold southerly fronts delivering a mixture of wintry conditions.
Further frosts this morning across much of the mainland indicate that winter isn’t too far away with clear skies seeing daytime heating escape.

I like to know what is “Normal weather” ?
As far as I’m concerned this winter will be dry and cold but dispersed with warm and wet periods
…or could be warm and dry but the occasional wet periods and be very cold???.

We agree – with no La Nina or El Nino to steer any particular weather pattern this winter we expect will have a real mixture of conditions with warm and wet and snowy and cold, also big, long, dry spells.
