WMO declares onset of El Niño conditions
According to the WMO projections, there is a 90 percent chance that the El Niño event will persist over the second half of 2023. It is predicted to be at least moderately strong.
El Niño episodes typically last between nine and twelve months and occur every two to seven years on average. It is a naturally occurring climate pattern linked to the warming of the tropical Pacific Ocean's central and eastern ocean surface temperatures.
