Climate Change Overview

Country Summary

This page presents high-level information for Grenada's climate zones and its seasonal cycle for mean temperature and precipitation for the latest climatology, 1991-2020. Climate zone classifications are derived from the Köppen-Geiger climate classification system, which divides climates into five main climate groups divided based on seasonal precipitation and temperature patterns. The five main 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).  Climate classifications are identified by hovering your mouse over the legend. A narrative overview of Grenada's country context and climate is provided following the visualizations.

Grenada is a small island country located at 11°58’ North latitude and 61°20’ West longitude, the southern end of the Caribbean island chain between the Caribbean Sea and Atlantic Ocean. Grenada consists of three islands with a total area of 345 square km (133 sq miles), which includes mainland Grenada, Carriacou, and Petite Martinique. Grenada is volcanic in origin, characterized by mountainous terrain with extensive corals and mangroves ringing the islands. Approximately 3% of the land area in the country is at sea level. The main towns and key socio-economic facilities are located on the coast. The highest point in the country is Mount Saint Catharine at 840 m. Grenada’s total population was estimated at 113,000 in 2020. The large majority of the population is of African descent (more than 80%). The Grenadian economy is mainly based on agriculture and tourism. 

Grenada is particularly vulnerable to the impacts of climate change, as evidenced by the impacts of extreme events and occurrences of increased forest fires, crop loss, water shortages and incidence of pests and disease occurring in recent years. Grenada's key economic sectors like agriculture and tourism are extremely vulnerable to the impacts of climate change.
