According to the U.S. National Oceanic and Atmospheric Administration, a record-breaking El Niño is developing in the Pacific Ocean and pushing global surface temperatures upward. This cyclical weather phenomenon, which weather forecasters warn could be the strongest El Niño this century, threatens to disrupt agricultural production and food security across multiple continents by triggering severe droughts in some regions and torrential rainfall in others.
How El Niño Alters Global Weather Patterns and Ocean Temperatures
During a typical El Niño event, trade winds that normally blow east-to-west across the tropical Pacific Ocean slow down or reverse, according to weather data from the National Oceanic and Atmospheric Administration. This atmospheric shift allows warm surface water that usually gathers near Southeast Asia to drift back toward the Americas. The cyclical pattern typically recurs every two to seven years and peaks around December or January, redistributing heat and moisture worldwide.
Average surface temperatures in the Pacific are projected to jump by more than 2 degrees Celsius, prompting forecasters to classify the event as a very strong or super El Niño. University of Maryland climate scientist Weston Anderson notes that because the phenomenon impacts a diverse set of geographies, there is no single set of uniform impacts.
Historical Parallels and Threats to Global Food Security
Severe climate disruptions tied to past super El Niños offer a stark warning for current agricultural markets. Washington State University associate professor Deepti Singh points out that the intense El Niño of 1877 coincided with historic droughts across Asia, Brazil, and northern Africa. Those droughts, combined with colonial policies, contributed to devastating global famines that resulted in upward of 50 million fatalities.
More recently, the strong 2023–24 El Niño—ranked among the five strongest on record by the World Meteorological Organization—helped drive global temperatures to historic highs. Arid regions relying strictly on rainfall for crop irrigation suffered immediate setbacks. In southern Africa, prolonged droughts fueled by that event escalated food insecurity and malnutrition, forcing vulnerable nations to lean heavily on early harvests and emergency food imports.
North African Rainfall Dynamics and the North Atlantic Oscillation
While the tropical Pacific drives global temperature anomalies, regional precipitation in places like Morocco depends heavily on atmospheric pressure systems thousands of kilometers away. Morocco endured six consecutive years of below-average rainfall between 2019 and 2024, culminating in the driest hydrological year in over six decades at just 106.4 mm, according to regional climate data. Per-capita renewable water availability dropped to roughly 620 cubic metres annually.
That multi-year dry spell ended abruptly in the winter of 2025–26 when Atlantic storms returned in force. Research highlighted by climate analysts shows that the shift was governed by the North Atlantic Oscillation. When the pressure gradient between the Azores and Iceland weakens, the high-altitude jet stream dips southward into the subtropics. This redirected storm track repeatedly funneled moist Atlantic air into Morocco, where the Rif and Atlas mountains forced it upward to soak the Sebou basin and refill depleted reservoirs.
Will the Super El Niño Bring Drought or Rain Back to Morocco?
Forecasters face a complex challenge determining whether the current super El Niño will trigger another wet winter in northwestern Africa or push the region back into drought. Strong El Niño winters can nudge the North Atlantic Oscillation into its negative phase late in the season, which historically favors wetter conditions across parts of Iberia and North Africa.
However, the Atlantic Ocean does not follow the Pacific as if connected by an on-off switch. Stanford University professor Jennifer Burney emphasizes that scientists are still actively observing and untangling how El Niño interacts with background global warming trends. The Pacific signal competes directly with the North Atlantic’s own powerful internal variability. During the 2023–24 El Niño, for example, forecasters anticipated a negative North Atlantic Oscillation phase that never materialized, demonstrating that El Niño loads weather dice while the North Atlantic ultimately throws them.
Did you know? South American fishermen named the phenomenon “El Niño”—referring to a little boy—because the warm coastal waters typically appeared around Christmas, associating the seasonal shift with the birth of Jesus Christ.
Frequently Asked Questions
What is a super El Niño?
A super El Niño is an exceptionally strong phase of the El Niño-Southern Oscillation cycle where average surface temperatures in the tropical Pacific Ocean rise by more than 2 degrees Celsius.
How does El Niño affect agriculture?
El Niño disrupts normal growing seasons by causing extreme weather events, including severe droughts in breadbasket regions and sudden heavy rainfall elsewhere, which can harm crop yields and escalate food insecurity.
Does El Niño guarantee heavy rain in North Africa?
