Our Organisational Structure
SLMet operates as a national agency under the Ministry of Transport and Aviation, bringing together diverse expertise to serve Sierra Leone's weather and climate needs. Our team of experts delivers comprehensive services across seven key areas: aviation meteorology for safe flights, hydrology for water resource management, climate services including seasonal forecasts, marine weather for coastal and offshore activities, environmental monitoring for air quality and sustainability, agro-meteorology to support farming communities, and daily weather forecasts for the general public. This multidisciplinary approach ensures we can provide specialized services for every sector of society - from farmers and fishers to pilots and government planners. We maintain weather stations across all regions and work closely with international partners to ensure our services meet world-class standards while addressing the unique needs of Sierra Leone's communities and economy.
