Spring westerlies kick-start September
Spring westerlies arrived during the first few days of September, and prevailed during the first half of the month. These stormy westerly quarter winds produced very wet conditions on the West Coast of the South Island, but in contrast, a rather dry month in eastern areas of both islands. From mid-month, a pattern change saw more anticyclones than usual lie over New Zealand and to the east of the country. This combination of patterns resulted in more northwest winds than normal over New Zealand for the month of September, overall.

La Nina gone by Easter; somewhat stormy Tasman Sea
A mature La Niña event in the tropical Pacific should be gone by Easter, according to the NIWA National Climate Centre. This means that local sea temperatures around our coast, and low pressure activity over the Tasman Sea, are likely to most influence our autumn climate.
