I have been plotting rainfall amounts on our property for over a decade. There is virtually zero correlation between an El Nino or La Nina year and the amount of rainfall. None. We have had both wet, drought, and average years worth of rainfall during both temperature extremes and moderate ocean temperature years. There may be some relationship between El Nino or La Nina events and weather patterns averaged over decades, but there is no predictive value in any particular year at all. None.
Come to Texas and claim this La nina doesn’t affect heat and rain. kalifornia is too close to the action of La and El to see major effects..
