The arrows show the direction of the average wind (1971–2000). New Zealand’s prevailing winds come from the west, and the country sits just north of the extreme westerlies further south. The climate is affected by the depressions (areas of low-pressure likely to cause clouds and rain) that develop in this westerly system. Near the equator the winds are easterly or south-easterly.
