Country Summary

This page presents high-level information for Dominica'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 Dominica's country context and climate is provided following the visualizations.

The Commonwealth of Dominica (Dominica) is situated between the Caribbean Sea and the North Atlantic Ocean. Dominica is a volcanic island with a series of complex mountain ranges, characterized by very rugged and steep terrain and volcanic peaks and cones of lava craters. The government has made strides in protecting the country’s spectacular biodiversity via an extensive natural park system and eco-tourism has recently become a mainstay of the economy. The agricultural sector accounts for about 17 per cent of gross domestic product and 14 per cent of employment, with crop production led by bananas. Due to its rugged inland topography, 90% of Dominica’s residents are located near the shore, as is most of the island's infrastructure, alluding to significant vulnerability to sea level rise, as well as flooding as Atlantic storms and hurricanes become stronger as a result of climate change.

The Environmental Coordinating Unit (ECU) is a unit established by a Cabinet Decision in 1999, to coordinate all environmental activities in Dominica. The overall function of the ECU is to bring about more focused environmental management approaches to the solving of Dominica’s environment problems, advise government of the development of more coherent environmental policies and enhance Dominica’s compliance with international treaties and conventions to which it is signatory. It also serves as the focal point for Multilateral Environmental Agreements to which Dominica is a party. Dominica ratified the Paris Agreement on September 21, 2016 and the associated Nationally Determined Contribution can be found here
