In Mandoul, Chad, sunshine duration reveals a fascinating seasonal rhythm that predominantly showcases an increase from early in the year leading into the summer months. Starting with 274 hours in January, the region experiences a steady rise in solar exposure, peaking in May with an impressive 346 hours of bright sunshine. This upward trend reflects the transition from the dry season to the onset of the wet season, as longer daylight hours coincide with increased temperatures. April also contributes to this trend, showing robust sunshine hours at 331, closely trailing May, which establishes a significant climate characteristic of the region.
As the peak sunshine months fade into the rainy season, the hours of sunlight remain relatively consistent with 330 hours recorded in June, maintaining a high level of daylight even amidst increased cloud cover. The following months—July and August—see slightly diminished sunshine, yet still robust with over 300 hours. Subsequently, September and October witness a gradual decrease, but they continue to hold on to substantial sunlight, ranging around 314 to 332 hours. Notably, despite the onset of the rain, Mandoul maintains a healthy balance of sunshine, reinforcing the region's tropical savanna climate and providing essential energy for its ecosystems. Overall, the year in Mandoul balances between bountiful sunlight and critical rainfall, underscoring the interconnected dynamics of climate and nature.
