Climate in Ghana
Climate change
Climate change is significantly affecting Ghana through rising temperatures, unpredictable rainfall, sea-level rise, and more frequent extreme events. Access to reliable climate information, such as the Ghana Climate Atlas, is essential to support planning, adaptation, and effective risk management.
- Access detailed Reports for in-depth climate analysis.
- Explore an interactive Mapviewer to see how climate changes over time and across different administrative level.
- Request for datasets to support further research and planning.
- Explore Story Maps featuring case studies of climate change impacts in Ghana.
- Browse our FAQs for concise answers to common questions.
Higher Temperatures
+1.4°C by 2100
Ghana is getting hotter, with rising average temperatures increasing heat stress across the country.
More Heat Waves
More frequent extreme heat
Hot periods will become more intense and frequent, especially in northern regions.
Variable Rainfall
Unpredictable seasonal changes
Rainfall will become less predictable, with shifts between wetter and drier seasons affecting planning.
More Flooding
Heavier rainfall events
Stronger rains, especially in peak seasons, will increase flood risks in many areas.
Rising Sea Levels
Up to 0.7m by 2100
Coastal areas will face increased flooding, erosion, and infrastructure damage.
Increased Drought Risk
Drier dry seasons (DJF)
Longer and harsher dry periods will raise drought, wildfire, and water stress risks.

Ghana
The Climate Atlas Mapviewer is an interactive tool designed to help users explore climate projection indicators.
Through the mapviewer, users can view annual and seasonal indicators of rainfall and temperature, and examine how these variables may change under different emission scenarios.
The platform also enables users to compare projections across scenarios and perform point or area-based analysis to calculate and view mean values for selected locations.
The projection in the map depicts the Average Annual Temperature for End of Century projections.
