1. Wet Season:
- Duration: The wet season occurred from May to October, bringing abundant rainfall to the region. These months were marked by heavy downpours and thunderstorms, especially during the peak of the season in July and August.
- Precipitation: Rainfall amounts could be significant, with annual precipitation reaching up to 1,000 to 1,500 millimeters (39 to 59 inches) in certain areas. This rainfall supported lush vegetation and fostered agricultural activities.
2. Dry Season:
- Duration: The dry season in ancient Ghana lasted from November to April, characterized by minimal rainfall and drier conditions. Although it was still warm during the day, nights could be relatively cooler.
- Harmattan Winds: This period was also influenced by the harmattan winds, blowing from the Sahara Desert. These winds carried fine dust particles, creating hazy atmospheric conditions and slightly cooler temperatures.
It's important to note that ancient Ghana covered a relatively large area, incorporating parts of present-day Ghana, Mali, Senegal, and Guinea. As such, there might have been slight variations in weather patterns across different regions of the empire. Nevertheless, the overall climate was consistently warm and tropical with alternating wet and dry seasons.
