The South-West Pacific Region is a vast area that includes part of Southeast Asia, Australia, New Zealand and the Pacific, encompassing 24 WMO Members that fall within the scope of the WMO Regional Office for Asia and the South-West Pacific. WMO Members in the Pacific sub-region are further supported by the Representative Office for the South-West Pacific (SWP). The region covers various climate zones and is prone to a wide array of climate and weather-related impacts, from heatwaves and droughts to cyclones and floods. Southeast Asia's climate is largely shaped by monsoons and trade winds, while the Pacific is influenced by La Niña and El Niño cycles. The region is also part of the seismically active Pacific Rim.

Over the past 50 years, the region has suffered 1,493 disasters, causing 66,951 deaths and $185.8 billion in economic losses. Tropical cyclones are the leading cause of these fatalities. The Southeast Asia sub-region includes countries like Malaysia and Indonesia, while the Pacific sub-region consists of Australia, New Zealand, and 14 Small Island Developing States. These islands are particularly vulnerable due to their low capacity for meteorological services.
