New Zealand Climate Update 238 - April 2019
30 August 2019
What happened in March how our climate outlook for the previous three months turned out, global and local sea temperatures, and our outlook for April-June.
The atmosphere continued to respond to a warm pool of water in the central and western equatorial Pacific, as evidenced by above normal rainfall and cloud cover across the region.
April–June2019 temperatures are forecast to be above average in the north and east of the North Island and east of the South Island (50% chance) and about equally likely to be above average (45% chance) or near average (40% chance) in all remaining regions of New Zealand.
The atmospheric circulation around New Zealand was forecast to be characterised by higher pressure than normal extending from the Chatham Islands to the Australian Bight.
