Science Centres: Climate

La Niña conditions are redeveloping in the tropical Pacific, and the event is expected to build through the coming spring and continue through summer. During late spring and early summer (October-December), mean sea level pressures are likely to be above normal across New Zealand, with weaker westerlies over the country, on average. 

Sea surface temperatures

Sea surface temperature anomalies have become increasingly negative in the east-central equatorial Pacific, negative sub-surface sea temperature anomalies have continued to strengthen, and low level easterly wind anomalies have been observed over the central tropical Pacific.
