The European Union's climate monitor warned Friday that sea surface temperatures could reach record highs this May [1, 2].

These rising temperatures are critical because they may serve as a precursor to a potentially devastating “super El Niño” weather pattern later in the year [1, 3]. Such an event could disrupt global weather systems and intensify extreme weather events across multiple continents.

Samantha Burgess of the European Centre for Medium-Range Weather Forecasts (ECMWF) said that sea surface temperatures in recent days were just shy of the all-time highs of 2024 [1]. She said that May looked set to break its own record [1].

The EU climate monitor is tracking the global ocean surface to determine if the current warming trend will lead to a sustained climate anomaly [2, 3]. The all-time high for sea surface temperatures was previously recorded in 2024 [1].

Climate scientists monitor these shifts to predict agricultural yields, rainfall patterns, and storm intensity. A “super El Niño” would represent a significant escalation in ocean warming, potentially leading to more severe droughts and flooding than seen in previous cycles [1, 3].

Officials continue to track the data as the month progresses to confirm if the record is surpassed [2].

The potential emergence of a 'super El Niño' suggests a period of extreme climatic instability. Because ocean temperatures drive atmospheric circulation, record-breaking heat in the surface waters can shift jet streams and moisture transport, increasing the risk of catastrophic weather events globally and complicating international efforts to manage climate-related food and water security.
