Climate, Rainfall, Seasons, and Environmental Hazards in Liberia

Liberia has a humid tropical climate strongly influenced by the Atlantic Ocean, the West African monsoon, elevation, and distance from the coast. Conditions differ by place and from year to year.

Rainy and dry seasons

The rainy season generally extends from late April into October, while the drier period generally runs from November into April. These are broad patterns, not fixed dates: onset, intensity, and local conditions vary across counties.

Rainfall and temperature

Coastal and southeastern areas are especially wet, while inland patterns are shaped by terrain and regional weather systems. High humidity and warm temperatures are common, with seasonal Harmattan influence sometimes reaching Liberia.

Environmental hazards

Flooding, coastal erosion, storm surge, landslides in susceptible terrain, wildfire, drought, extreme heat, and disease risks can affect communities, agriculture, infrastructure, and ecosystems.

Climate change and planning

Resilience depends on reliable observations, drainage and land-use planning, early warning, protected wetlands and forests, climate-informed agriculture, safer construction, and public access to trustworthy information.
