While the 2020-21 La Nina has not officially ended, observations show that the
central Pacific SSTs have reverted to near normal over the last few weeks, bringing
the event to at least a temporary end. Neutral ENSO conditions are likely to persist
through early summer.
The Pacific warmed slightly in November overall, but atmospheric and oceanic conditions still reflect a warm-neutral ENSO state. WeatherTiger’s ENSO Whisperer output expects that ENSO will stay in neutral conditions into early 2020, with El Nino odds increasing a bit into the spring months.
