The Pacific Ocean is running a fever. In October, equatorial sea surface temperatures hit 4 degrees Celsius above normal—a record high since observations began in 1949. This heat is acting as rocket fuel for storm systems, pushing the accumulated cyclone energy (ACE) index for South-East and East Asia to nearly double its 30-year average.
The physical toll is already visible. In the Philippines' Batanes archipelago, coastal highways buckled under enormous waves. In Japan’s southern Okinawa islands, 15,000 households lost power. The sheer scale of these systems is defying standard tracking; Typhoon Chan-hom recently traversed Japan from east to west, a rare trajectory that caught even seasoned meteorologists off guard.
Ana Liza Solis, head of climatology at the Philippines' national weather bureau, described the ocean as "burning with fever" during a September press briefing in Manila. Her team’s simulations suggest warmer conditions are lengthening the storms' lifecycle, allowing them to gather more strength over water before making landfall. The UK Met Office has flagged this episode as potentially the strongest in living memory.
Governments are scrambling to adapt. In June, Japan evacuated nearly one million people when Typhoon Mekkhala and Severe Tropical Storm Higos converged on its eastern coast. Neighboring nations are bracing for a similar onslaught. The Japan Meteorological Agency projects these extreme conditions will persist until February or March, keeping the region on high alert as the season shifts.
