  The El Ni\~no Southern Oscillation (ENSO) is the most important driver of
interannual climate variability and can trigger extreme weather events and
disasters in various parts of the globe. Recently, we have developed two
approaches for the early forecasting of El Ni\~no. The climate network-based
approach allows forecasting the onset of an El Ni\~no event about 1 year ahead.
The complexity-based approach allows additionally to forecast the magnitude of
an upcoming El Ni\~no event in the calendar year before. Here we communicate
the forecasts of both methods for 2021. The methods indicate a high probability
(about 89% and 90%, respectively) for the absence of an El Ni\~no in 2021.
