Island Climate Update 194 - November 2016

Download the PDF: Island Climate Update 194

The tropical Pacific exhibits mixed ENSO (El Niño-Southern Oscillation) signals, with some indicating La Niña status and others indicating neutral conditions.

International guidance still slightly favours La Niña conditions (53% chance versus 46% for neutral) over the next three month period (November 2016 - January 2017). However, neutral conditions are now much more likely than La Niña by February – April 2017: 74% chance for neutral, and only 22% for La Niña. In summary, La Niña conditions are only slightly more likely than not over the next 3-month period, and become less likely as we progress into 2017.
