Tropical Monsoon Climate Patterns
The Con Dao Islands’ tropical monsoon climate is marked by consistently warm temperatures and distinct wet and dry seasons. Unlike many parts of Vietnam, Con Dao’s climate is heavily influenced by its island geography, creating weather patterns that can differ significantly from the mainland.
