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 Jamaica.

Impacts Water

Impacts from climate change can affect water availability, water quality, and water management. Climate change projections estimate that Jamaica will have a decrease of annual runoff of 15% or higher. An increase in extreme weather events with heavy precipitation could pollute waterway and affect water resources, including beaches and near shore water quality. Factors that reduce water management systems such as sea level rise and precipitation can create environments for vector borne diseases. Rising temperatures are also expected to require increased cooling aids, which would further require water for electricity production. Rising sea levels can also impact aquifers through salt water intrusion.

This section allows you to gain insights into climate change impacts on hydrological statistics based on climate future scenarios.


Data presented under Historical Climate Conditions are reanalysis products derived from ERA5-Land data. ERA5-Land is a global land-surface dataset at 9 km resolution, consistent with atmospheric data from the ERA5 reanalysis from 1950 onward. Climate reanalyses combine past observations with models to generate consistent time series of multiple climate variables. They provide a comprehensive description of the observed climate as it has evolved during recent decades, on 3D grids at sub-daily intervals. 

This data has been collected, aggregated and processed by the Climate Resilience Cluster of the European Space Agency’s (ESA) Earth Observation for Sustainable Development (EO4SD) initiative.
