Country Summary

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

The islands of St. Kitts and Nevis are located in the northern part of the Lesser Antilles. The topography of the islands consists of a mixture of lowlands, which are used for development or farming, and slopes, which are mainly associated with volcanic mountain ranges. The coastal and marine waters of St. Kitts and Nevis host a range of ecosystems including coral reefs, freshwater lagoons, seagrass beds and mangroves. Gross domestic product for the country in 2014 was estimated at US $833.3 million, giving the country a “high income” status. Major economic sectors in the country include banking and insurance, wholesale and retail trade, construction, and manufacturing, with agriculture playing a less significant role. With over 60% of the population residing in coastal areas and a substantial coastal tourism sector, the country is significantly vulnerable to sea level rise and the threats of accelerated coastal erosion and flooding. These threats are exacerbated by human-induced deforestation and steep slopes throughout the country. 

The Department of Environment under the Ministry of Agriculture, Marine Resources, Cooperatives, Environment and Human Settlement is the lead agency for environmental management. The National Conservation and Environmental Protection Act (NCEPA) provides the legislative authority for the management and development of natural and historic resources in St. Kitts and Nevis. The purposes and objectives of NCEPA have linkages to climate change adaptation and other aspects of sustainable development. St. Kitts and Nevis ratified the Paris Agreement on April 22, 2016, and its Nationally Determined Contribution (NDC) can be found here
