Overview 

This week will be dominated by a storm around southern NZ bringing gale westerlies, periods of rain and/or showers and cooler/colder changes. The Southern Ocean has had a particularly unsettled weather pattern (something we exclusively forecast in November) and even though we're now entering 'peak summer' will may be a few road bumps this week. The storm centre this will brush the lower South Island and brings rain and showers to the west of both islands, especially the West Coast, and a surge of gale west to north west winds - damaging for some. Southland and Otago will have daytime maximums of just 9 to 12 degrees in some locationson Wednesday with snow on the ranges. High pressure returns this weekend.



14 Day Outlook 2021 01 18 at 8.41 AM

High pressure is fading over NZ with low pressure south of the country dominating across this week, until about Thursday/Friday. The weather pattern will be more settled in the very north and windiest in central and southern parts of NZ. This week is quite unsettled for the middle of summer with a more spring/autumn look to the weather pattern. However more settled high pressure should return by Friday/this weekend with temperatures increasing again. 



Weather Trends

RAIN

We see showers and some periods of rain moving in from the west over the next week or so due to these Southern Ocean lows and westerly airflows. For the western side of both islands (up to about Auckland) rainfall over the next several days will be around normal for this time of year. For those in the east of both islands and from about Auckland northwards rainfall still looks to be slightly below normal. The West Coast is wettest by far.

WIND

Westerly winds will dominate much of NZ this week with the windier change especially noticeable on Tuesday from the west due to another bigger low south of NZ which will generate gale, even damaging, westerly quarter winds for some, easing Wednesday. Calmer by Friday.

TEMPS

Some hot days coming with temperatures leaning above average to start with, but that does change mid week with a much cooler change coming by Wednesday. In Southland and Otago it's highly likely some will fail to even reach the teens by Wednesday or Thursday.

HIGHLIGHTS

Tuesday gales may be damaging especially in eastern and central NZ. Rain accumulations on the West Coast this week over 200mm. Waves up to 13 metres on the southern half of the West Coast. Drier than normal still in the very north and east of both islands next 7 days.
