The Weekend's situation

19th-20th January 2019

Weather Weekend Template

High pressure dominates New Zealand on Friday with mostly dry, warm, weather across the country. On Saturday a disturbance in the Southern Ocean will bring heavy rain to the West Coast, patchy rain for Southland & Otago and windier westerlies from Cook Strait southwards. Sunday is cooler with a SW flow.

A westerly shift is coming for the South Island which means the highs will be a little further to the north/north west. This will allow windier weather to push into the South Island and Cook Strait at times, with the odd cold front heading north with a cooler southerly behind it. Places like Southland, Otago and the West Coast will have fluctuating temperatures which will make it feel more like Autumn than mid-summer with a combo of hot days and cool ones (some coastal parts of Southland may only have highs in the low teens this Sunday and Monday). Most places are drier than average in the week ahead but heavy rain for the West Coast this Saturday and next Wednesday.

Positive weather for pasture growth in the next week with temperatures lifting back up again and in many regions it will be warmer than average. Not all will have this warmth with the lower South Island (regions like Westland, Southland and Otago) receiving fluctuating temperatures more like in Autumn or Spring. Recent rain over the North Island will now couple with sunny, calm, weather ensuring a jump in pasture growth rates. Facial eczema conditions remain low with good weather conditions.

Heavy rain for the West Coast this weekend and again mid through next week. Some spillover patchy rain for Southland and Otago. Other than that, most other regions look drier than normal for the next week ahead.


Westerlies will pick up this weekend and become blustery on Saturday in some areas in the South Island and around Cook Strait later. Next Wednesday we have a similar performance then more high pressure calms things down. Nothing extreme.


Warmer weather for most regions over the next day or two but a colder change arrives in the South Island on Sunday and Monday and will spread further north before fading. Another cool change mid next week in the south too.


Heavy rain this weekend on the West Coast, watch for possible rain warnings. Winds will also be blustery for a time this weekend. On Sunday daytime highs will drop to the teens in the lower South Island.
