Southeast, South and East Asia experience the most tropical cyclone clusters worldwide. The Philippines, Vietnam, Laos, India, Pakistan, Sri Lanka, Japan, Taiwan and China are particularly at risk.
With an average of 20 typhoons per year, the Philippines is the country most affected by tropical cyclones in the world. In November 2025, the country was struck by back-to-back typhoons, Typhoon Tino and Super Typhoon Uwan. The combined death toll of both typhoons in the Philippines amounted to 297 deaths, with hundreds of others injured and missing. Several airlines cancelled hundreds of flights across the country on 9-12 November 2025, with related road closures in Bicol and Central Luzon regions lasting for several more days. Around 1.5 million people were pre-emptively evacuated ahead of Uwan’s landfall, which carried maximum sustained winds of 185kph (114mph).
In April, Super Typhoon Sinlaku made landfall in the Northern Mariana Islands and affected Guam and Micronesia. Sinlaku, designated as a category 5 storm on the Saffir-Simpson wind scale (the strongest category), holds the title as the strongest cyclone globally since the start of 2026. At its peak, the storm produced maximum sustained winds of around 297kph (185mph). Sinlaku caused widespread damage to civilian infrastructure, travel disruptions and the deaths of five people.
The tropical cyclone season in Australia generally lasts from November to April. An average of 11 tropical cyclones occur in the region annually, although only some of these reach the mainland. The 2025-26 cyclone season in the Oceania and South Pacific regions saw a series of strong tropical cyclones hitting the Australian coast and surrounding areas. The most powerful was Tropical Cyclone Maila, which strengthened to a category 5 between the Solomon Islands and Papua New Guinea (PNG) in early April, causing dozens of deaths and severe damage to homes, businesses and critical infrastructure, including emergency services. The storm triggered widespread power outages and disruptions to food and other essential supplies in parts of East New Britain province and Bougainville region in PNG. Tropical Cyclone Narelle hit multiple parts of northern Australia in March, causing major flooding and widespread economic damage. A similar scenario occurs in Tuvalu, Samoa, Fiji, Tonga and Vanuatu, experiencing an average of six cyclones per year.
Tropical cyclones in the North Indian Ocean typically form between December and April, peaking from May to early November. The northern Indian Ocean is divided into two sub-basins: the Bay of Bengal and the Arabian Sea. The countries most affected by these areas are India, Bangladesh, Sri Lanka and Myanmar, while Pakistan and Oman are occasionally affected. It has produced some of the world’s deadliest tropical cyclones, affecting densely populated areas. The last major tropical cyclone of the 2025 season occurred toward the end of the year, during the peak post-monsoon period. Cyclonic Storm Ditwah hit Sri Lanka and southern India in late November 2025. It was relatively weak but catastrophic, triggering severe flooding and more than 600 deaths.
