30 August 2019
What happened in June how our climate outlook for the previous three months turned out, global and local sea temperatures, and our outlook for July-September.
During June2019, sea surface temperature anomalies remained above El Niño thresholds (i.e. +0.70 ̊C) in the central Pacific for the fourth consecutive month
July – September 2019 temperatures are about equally likely to be near average (40-45% chance) or above average (40-45% chance) for all regions of New Zealand. Despite a low chance for a season with below average temperatures, cold snaps and frosts remain likely to occur.
New Zealand’s regional climate over April – June 2018 was expected to be driven by persistence of more northeasterly airflow than normal.
