State of the Climate in Asia 2025 is a climate report published by the World Meteorological Organization (WMO) in 2026. It provides a regional assessment of climate conditions in Asia during 2025, focusing on temperature, precipitation, glaciers, oceans, sea level, extreme events, climate drivers, and climate-related impacts and risks.
Key insights:
The report shows that 2025 was one of the warmest years on record for Asia, with the mean temperature 0.96°C above the 1991–2020 average, ranking between the second and fourth warmest year for the region.
Asia is warming faster than the global average. The report notes that the warming trend in Asia during 1991–2025 was approximately twice as strong as the trend during 1961–1990.
Southern Asia experienced above-average precipitation, with exceptionally heavy monsoon rainfall. In Pakistan, monsoon flooding was associated with more than 1,000 deaths and left over 3 million people requiring assistance.
Viet Nam also experienced prolonged flooding linked to multiple weather systems, causing at least 200 deaths and around US$ 1.9 billion in economic losses.
West and Central Asia experienced below-average precipitation and prolonged dry conditions. In the Islamic Republic of Iran, long-term drought contributed to water shortages.
The report highlights severe cryosphere changes. All 23 monitored glaciers in High-mountain Asia lost mass, driven by above-average temperatures and below-average winter snow.
Ocean heat content in Asia reached a new record in 2025, and marine heatwaves affected almost the entire ocean area of Asia, with more than 10 million km² impacted during July–September.
Sea level is rising faster than the global mean in much of the northern Indian Ocean, including around 4.9 mm/year along the Indian coast and around 6 mm/year in the Kuroshio Current region.
Tropical Cyclone Ditwah caused extreme rainfall in Sri Lanka, with 10% of the annual rainfall total recorded in 24 hours. The event led to more than 640 deaths, displaced more than 200,000 people, and caused major economic losses.
The report stresses the importance of observations, early warning systems, impact-based forecasting, and preparedness to reduce losses and help countries adapt to increasing climate risks.
Main message: Asia is facing intensifying climate risks, including rising temperatures, heavier rainfall and flooding, drought, glacier loss, marine heatwaves, sea-level rise, and damaging tropical cyclones. Strengthening early warning systems, impact-based forecasting, climate observations, and preparedness is essential to protect lives, livelihoods, infrastructure, food systems, water resources, and public health.
