State of the Climate in Asia 2025—Impacts, Risks, and Key Findings

The latest annual World Meteorological Organisation (WMO) State of the Climate in Asia 2025 report was released in June 2026. The report complements the State of the Global Climate 2025 report – both are annually released WMO reports that deliver a summarised and consolidated assessment of Asia’s climate conditions from the previous year.

The report aims to provide information to national hydrological and meteorological services in Asian countries, policymakers, scientists, the media, educators, and the public.

The State of the Climate in Asia 2025 provides authoritative information on key climate indicators, major extreme events, impacts and risks. It includes case studies which demonstrate the scale of the risk and the need to strengthen impact-based forecasting and preparedness on what the weather will DO, rather than simply what it will BE.

The report stated that in 2025, record ocean heat, dangerous heatwaves, destructive rainfall and floods, glacier loss and severe drought affected Asia, affecting millions of people across the region and causing economic losses.

Key findings of the report

Ocean warming has increased since the 1990s and reached a new record in 2025, affecting most of Asia’s ocean areas, with over 10 million km2 affected during July to September. Continued ocean warming and acidification, driven by rising GHG emissions, are threatening marine ecosystems and coastal communities through sea level rise.

All 23 monitored glaciers in the region’s high mountains experienced mass loss driven by rising temperatures and below-average winter snowfall. Less snowpack in the winter can threaten water security in the world’s most populous region.

Asia has been warming faster than the global average over the past few decades. The annual mean temperature in the region was 0.96 °C above the 1991–2020 average, making it the second- and fourth-warmest year on record, depending on the dataset used.

Warming trends between 1991 and 2025 are around twice the rate as those between 1961 and 1990. The 2025 summer season was the hottest recorded in Japan, China, and Korea.

2025 has seen above-average precipitation. Rainfall from tropical cyclones has led to devastating floods in Pakistan, Sri Lanka and Vietnam. Flooding resulted in 1,000 deaths and left 3 million people requiring assistance in Pakistan. Prolonged flooding in Vietnam has led to 200 deaths and US$1.9 billion in economic losses.  

Below-average precipitation and prolonged dry conditions were observed in West and Central Asia, while long-term drought has contributed to water shortages in Iran.

The State of the Climate in Asia report highlights how climate change impacts are wreaking an ever-increasing human, financial and environmental toll, worsening food insecurity and poverty and holding back sustainable development.
