Rain clouds and sub-tropical winds are returning to northern NZ this week, despite high pressure dominating to kick the week off. High pressure skirted past NZ over the weekend and it is today slowly moving out to our east and by the end of Tuesday it departs our shores properly.

Behind it we have a wet sub-tropical northerly flow which gives way to being windy westerly quarter winds by the end of the week.

We also have a pool of low pressure moving into NZ either this weekend or early next week for a time.

This set up will likely feel spring-like, especially in the North Island.

Also with low pressure likely moving into country this weekend or next week one positive for southern NZ is that these set ups can produce easterlies – which may see some rain or showers into dry parts of Southland, Otago and Canterbury from this coming weekend. Keep an eye on for more as this set up is changeable next week.

Put simply, the North Island and upper South Island may well lean wetter than average over the next week. More good news for Auckland’s water storage area.
