Relationship between the Oceanic Niño Index (ONI) and air temperature departures by season for all years between 1925 and 2022 using a trailing 30-year climatology. The darker the color, the stronger the connection. Positive correlation means ONI values and temperature vary in the same direction: when ONI is higher (El Niño), temperature is higher, and when ONI is lower (La Niña), temperature is lower. Images by Brian Brettschneider, using ONI values based on Climate Prediction Center methods and Alaska temperature departures based on Climgrid data from NOAA National Centers for Environmental Information.
