La Niña is likely to continue through the Northern Hemisphere winter 2020-2021 (~95% chance during January-March), with a potential transition during the spring 2021(~50% chance of Neutral during April-June).
La Niña persisted during November, as indicated by well below-average sea surface temperatures (SSTs) extending from the Date Line to the eastern Pacific Ocean (Fig. 1). Most of the weekly indices fluctuated through the month, with the westernmost Niño regions Niño-4 and Niño-3.4 ending up around -1.0ºC.
