What You Need to Know
• The World Meteorological Organization warns of increased heatwaves, droughts, and heavy rainfall due to El Nino.
• El Nino conditions are expected to strengthen rapidly between July and September 2026, according to the WMO.
• Global ocean temperatures reached a record high in June 2026, partly attributed to the El Nino phenomenon.
The World Meteorological Organization (WMO) has issued a warning regarding the potential for extreme weather events, including heatwaves, droughts, and heavy rainfall, as a result of the El Nino weather phenomenon. The WMO stated that El Nino conditions have already begun and are projected to intensify significantly between July and September 2026. Historically, El Nino events peak from November to February, and the organization has activated climate information services and early warning systems to assist governments and humanitarian agencies in preparing for the impacts on farmers and vulnerable communities. WMO Secretary-General Celeste Saulo emphasized the importance of advanced seasonal forecasts and early warnings to mitigate risks associated with these extreme weather conditions.
Why It Matters
Understanding the implications of El Nino is crucial, as it affects global weather patterns and can lead to significant economic and humanitarian challenges. The phenomenon alters surface temperatures in the central and eastern equatorial Pacific Ocean, influencing wind, pressure, and rainfall patterns worldwide. Previous El Nino events have been linked to record-high global temperatures, with 2023 being the second-hottest year on record and 2024 projected to surpass it. The ongoing monitoring and forecasting by the WMO are essential for preparing communities and minimizing the adverse effects of these climate changes.
