Another cool change is on the way for parts of the South Island as summer-like weather finally spreads across the entire country this week.

A large anticyclone is currently pushing in from the west bringing mostly sunny skies, cool mornings and hot afternoons to New Zealand.

Southland and Otago are also enjoying the sunnier weather – but once again a southerly is approaching.

Thankfully this one will fall apart as it hits the South Island overnight Wednesday and into Thursday morning, but it will still bring in cooler temperatures.

Daytime highs in more coastal parts of Southland and Otago will slip from the low to mid 20s on Wednesday, to just 15 degrees on Thursday.  This affects both Invercargill and Dunedin. Despite mostly dry weather in the forecast for the rest of the week and weekend the highs aren’t going to rocket back up – hanging around the mid teens into the first few days of February.

Christchuch will also be affected by the weather change. Highs will drop from the mid-20s to late teens, so not as cold as further south. However cloudy, drizzly, weather may hang around for Thursday and Friday. The weekend looks brighter but highs only around 19.

Despite the southerly, it is significantly weaker than other southerly changes this month.

Rain will weaken to drizzle and patchy showers as it moves north on Thursday, delivering very little to farmers, garderns and those in need of rain water.
