Weekend Outlook

MetService meteorologist Kgolofelo Dube says “The South Island is in for a treat this weekend, with plenty of sunshine, perfect for enjoying snow-capped views, getting outdoors, or hitting the ski fields across Canterbury, the Southern Lakes, and Central Otago.”

While ski conditions are expected to be excellent, some valleys may experience thick fog at times.”

Meanwhile, the North Island is likely to continue seeing periods of rain across several regions. Fieldays in Hamilton has so far experienced showery and windy conditions. The good news is that more settled weather is expected to arrive from late Friday into Saturday, a welcome change for eventgoers.

By Sunday, a high-pressure system is expected to move in from the south, bringing more settled and sunny conditions to much of the country, though a few showers may linger in places.

Temperatures for the South Island will remain low, with overnight temperatures near or below freezing. This will keep snow on the mountain tops and frosty conditions in sheltered areas. A noticeable temperature drop is expected across the North Island early next week, something to keep an eye on as we head into the new week.
