St. Vincent and the Grenadines

Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. Explore the overview for a general context of how climate change is affecting St. Vincent and the Grenadines.


Overall risks from climate-related impacts are evaluated based on the interaction of climate-related hazards (including hazardous events and trends) with the vulnerability of communities (susceptibility to harm and lack of capacity to adapt), and exposure of human and natural systems. Changes in both the climate system and socioeconomic processes -including adaptation and mitigation actions- are drivers of hazards, exposure, and vulnerability (IPCC Fifth Assessment Report, 2014).

St. Vincent and the Grenadines is at risk to several natural hazards, including floods, hurricanes, cyclones, droughts, landslides, and volcanic eruptions.

This section provides a summary of key natural hazards and their associated socioeconomic impacts in a given country. It allows for a quick assessment of most vulnerable areas through the spatial comparison of natural hazard data with development data, thereby identifying exposed livelihoods and natural systems.

Key Vulnerabilities

  • Since 1900, Saint Vincent has been hit by 8 storms, the strongest being Category 4 Hurricane Allen, which passed between Saint Lucia and Saint Vincent in 1980. Hurricane Hazel (Category 1), and Hurricane Lenny (Category 4) have also severely affected the country.
  • Being in the path of the Atlantic hurricane belt, the most common threat to this country is the potential for hurricanes and tropical storms. High winds and rainfall, coupled with the mountainous terrain, are the principal risk factors.
  • Landslides, mainly on the larger islands, are significant hazard risks and the risk is elevated during the seasonal rains. Coastal flooding is also a major concern, particularly relating to storm surges and high wave action.
  • The Grenadines have no rivers and rainwater harvesting is their main source of water. Hence, they are more susceptible to drought.
