This coming winter is more likely than not to see below average irradiance across most of North America, as the impacts of El Niño bring cloudier, wetter conditions across the continent. Analysis of Historical Time Series data from El Niño years using the Solcast API, shows that irradiance is significantly impacted in these years. The National Oceanographic and Atmospheric Administration (NOAA) has declared that we are in El Niño’s Southern Oscillation (ENSO) phase, and that there is a 90-95% probability this will continue into the upcoming winter. NOAA has further forecast a 60% chance that this will be a “strong event,” so solar producers across the continent should be anticipating this to change their expected performance through the winter. https://www.activistpost.com/2023/08/el-nino-threat-puts-us-solar-power-output-at-risk-this-winter.html
