There are signs pointing towards El Niño developing over the summer. The models aren’t very strong with the nino right now, but historically after 2nd and 3rd year Ninas we have seen stronger ninos. After the 3 year Nina ending in 2001 and the 2 year Nina ending in 2009, a moderate or strong El Niño developed! There is a lot of warm water below the surface in the western enso 4 region, these waters are as much as 6 degrees Celsius above normal. It will spread out as it comes up so we won’t see anything near a +6 ONI, but waters that warm do often result in fairly powerful El Niños such as 2009-2010, 2002-2003, 1957-1958, 1972-1973, 1982-1983 etc.
