Super El Niño, a rare climate phenomenon, is anticipated to develop this year, potentially leading to erratic weather patterns in the UK. Experts from AccuWeather warn that this event could result in heavy rainfall and heatwaves, with a 25% chance of intensification into a Super El Niño by fall or early winter. This phenomenon is characterized by warmer surface waters in the central and eastern Pacific, which can significantly alter global weather patterns. Historically, there have been 27 El Niños since 1950, with only five classified as Super El Niños, the last occurring between 2015-16. The impacts of a stronger El Niño may include increased global temperatures and shifts in storm tracks across the Atlantic, affecting how winter storms develop. While uncertainty remains regarding the strength of this year's event, meteorologists are increasingly confident that at least a moderate El Niño will occur.
