As we end October and head into November the weather pattern shows plenty of high pressure systems affecting our country – tilting the rain clouds into certain regions and keeping other areas mainly dry.
November often has quiet repetitive weather in New Zealand – a long way from the depths of winter but still not quite inside the calm side of summer.
Highs north of New Zealand encourage hot humid northerlies over both islands – and westerlies.
Highs directly over the country encourage calmer, drier weather over NZ – and sometimes leaves the sub-tropics more exposed to lows and rainmakers affecting the north.
If the highs track further south in November then the negatives might be fewer rain events for Canterbury and an uptick in lows (or at least unsettled areas) north of New Zealand and that could bring in more cloud, humidity and wet weather for the upper half of the North Island. The positives would be less wind and more sun for many others.
At this stage we see no major shift in the weather pattern as we slide into November but we may see a slight uptick in high pressure around the country as we continue to track into summer.
We”ll have a more detailed outlook for November on Monday October 31st but the first week of November looks like it will have westerly quarter winds over most regions and perhaps an increase in high pressure.
