September: Ethereum’s Historically Weak Month
Ethereum’s track record in September confirms recurring challenges, with average returns standing at -6.17%. Historical data shows the month has produced more red candles than green.
In 2020, Ethereum dropped -14.97%, and 2022 mirrored the trend with a -15.26% decline. These double-digit losses strengthened September’s reputation as a difficult trading month for the asset.

The exception was 2021, when Ethereum recorded an impressive +40.01% surge, proving that while bearish tendencies dominate September, strong bullish momentum can still defy the pattern.
October and November: Consistent Recovery Periods
The market has often experienced recovery immediately after September. Historically, October has delivered an average gain of +6.66%, positioning it as the start of a rebound phase.
November has followed with an average return of +6.48%, continuing the recovery cycle. These months frequently offset September’s weaknesses, restoring market sentiment during the final quarter.
Analyst Cipher X noted on X that if September remains soft, October and November may again prove favorable for Ethereum. His post highlighted that these two months have historically flipped positive after September setbacks.
December: Strengthening Year-End Momentum
December has historically maintained the positive trend, averaging +7.73% in returns. This performance makes it one of Ethereum’s stronger months in the yearly cycle.
The closing quarter has often brought renewed momentum as market participants position for year-end. This seasonal trend suggests that September downturns are frequently followed by solid rebounds.
Cipher X emphasized that while September may appear choppy, the months that follow have historically delivered far more favorable conditions for Ethereum. His analysis suggested that Q4 often resets the market for sustained gains.
