Another cool change is moving up the South Island while North Islanders are watching another possible sub-tropical low. Firstly, in the deep south, the unsettled cool weather continues as yet another cold front moves in. The good news is that this front is very weak - and it’s good news for apple growers too who are loving the cooler mornings. However in the upper North Island all eyes are on another sub-tropical low. While the data is still a bit unsure about where exactly this low will end up (likely East Cape or east of there) it is likely to affect our weather in some ways.
