Country Summary

This page presents high-level information for St. Vincent and the Grenadines's climate zones and its seasonal cycle for mean temperature and precipitation for the latest climatology, 1991-2020. Climate zone classifications in the map below use observed, historical data (sourced from the Climate Research Unit [CRU]) and are derived by applying the Köppen-Geiger climate classification methodology. This classification divides climate into five primary climate groups, which are divided based on seasonal precipitation and temperature patterns. The five primary groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar). All climates, except for those in the E group are assigned a seasonal precipitation sub-group (second letter). It is important to understand the different climate contexts that exist within a country as well as the surrounding region when analyzing current climates and projected change. Climate classifications are identified by hovering your mouse over the legend. A narrative overview of St. Vincent and the Grenadines's country context and climate is provided following the visualizations.

Saint Vincent and the Grenadines is a small country located in the Eastern Caribbean, consisting of over 30 islands, inlets and cays. These islands are part of the Windward Island chain of the Lesser Antilles. The main island is mountainous and rises 1,234 m to the volcanic cone of Soufriere. From Soufriere, the rugged hills slope to the sea and then collapse to several little islets and cays that form the Grenadines. Out of the total population of approximately 110,947 (2020) people, about 91% live on mainland Saint Vincent and the rest live on the Grenadines. The country’s economy is heavily dependent on agriculture and tourism, but the agriculture sector has declined by about 7.4% since 1990. Banana is the most important agricultural commodity and accounts for the major percentage of agricultural exports. The country is vulnerable to the impacts of climate change from extreme weather events and natural disasters which would increase the risks on its economy.
