Its cyclical and comes in cycles. Historically, it has occurred at irregular intervals of 2-7 years and has usually lasted one or two years.

Therefore it comes and goes ever once in a while. It should be back, but with the increased ocean temperatures and decreased salinity i guess its not guaranteed (Global Warming).

El Niño and La Niña are officially defined as sustained sea surface temperature anomalies of magnitude greater than 0.5°C across the central tropical Pacific Ocean. When the condition is met for a period of less than five months, it is classified as El Niño or La Niña conditions; if the anomaly persists for five months or longer, it is classified as an El Niño or La Niña episode.

El Nino is part of a long-term global cycle involving both the ocean and the atmosphere, the El Nino/Southern Oscillation (ENSO). At the present time, the ENSO is in the process of switching from neutral to positive, indicating that El Nino conditions are likely to develop in the next few months. A full cycle, from one El Nino to the next, takes several years, but there is a great deal of variability in the length of the cycles, and it is too early to tell how severe the upcoming El Nino will be.

Well, we are just waiting its next return. If everything goes as predicted it will appear around the month of December during the next 4 years.

Why December? because the temperature change initiated in the central Pacific Ocean triggers the anomaly which usually presents itself at that time of the year in front of the Pacific coast of Southamerican countries (Colombia, Ecuador, Peru and Chile), thus it was called "El Niño" because in Spanish language means "The Boy", as in the coming of a baby boy... baby Jesus who was born in December.

As for its next appearance, no body knows for sure. It all depends on the upcoming winter which will set the parameters to analyze if one it’s going to present next year. So far the next "El Niño" predicted to be very severe with a drought event is spected around 2012 in the island of Papua New Guinea, according with the Pacific Islands Report from the Pacific Islands Development Program/East-West Center.
