As earlier forecasted, El NiƱo will reach its peak somewhere between late fall and early winter and as we approach the apex of what many are referring to as a “Godzilla” El NiƱo, here’s what we can expect precipitation-wise out of this year’s historic meteorological phenomena.
In ENSO’s latest blog post,Ā El NiƱo update: Pumpkin spice,Ā Emily Becker describes the upcoming trend and its correlation to precipitation as variable at best. She admits a ton of variation when looking at previous El NiƱo events from the past and their subsequent precipitation amounts. However, with all the disclaimers out-of-the-way her finding’s paint a very optimistic picture, especially for Northern California and the Sierra’s.
Below is the average of El NiƱo years starting in 1950 and their collective precipitation amounts

Basically, El NiƱo years offer an average of 40 precipitous days in northern California during the winter months compared to 29 during a non El NiƱo year.
“Hereās a fun fact for your next nerdy cocktail party⦠Boulder, Colorado has registered seven October snowstorms with more than one foot of snow since 1950, every one happening during an El NiƱo winter.”- Emily Becker (NOAA blogger)
Below is an average of heavy rain days (or days when it will puke) during El NiƱo years since 1950

During an El NiƱo year, heavy precipitation days are more than twice as likely when compared to that of a non El NiƱo year.
Actually normal years contain 4 days of heavy precip compared to about 8.5 days during an El NiƱo year! That’s good news for California…
