Climate

The Sierra Leone Meteorological Agency (SLMet) provides comprehensive climate information and services to support national development, climate adaptation, and resilience building across Sierra Leone's diverse sectors. Understanding Sierra Leone's tropical monsoon climate—characterized by distinct wet seasons (May to November) and dry seasons (December to May) with harmattan winds—is crucial for effective planning and decision-making. Our climate services combine long-term climate data analysis, seasonal forecasting, and climate change projections to help government agencies, businesses, communities, and researchers understand climate patterns, prepare for climate variability, and adapt to changing conditions. With average temperatures ranging from 26°C to 36°C and rainfall varying from 2000mm in the east to 5000mm along the coast, we provide location-specific climate information that supports everything from agricultural planning to infrastructure development and disaster risk reduction.
