This period supports robust agricultural activity and replenishes local water sources. Following the heavy rains, September sees a rapid decline in precipitation to 150 mm (5.9 in), while October brings a further drop to 41 mm (1.6 in). As the year concludes, November and December return to dryness, with minimal rainfall recorded, highlighting the definitive seasonal cycle of Tandjilé's climate.
In Tandjilé, Chad, sunshine duration showcases a remarkable annual rhythm, with a clear trend of increasing hours of sunlight from the cooler months to the peak of the dry season. Beginning with 273 hours in January, the sun's presence gradually intensifies, reaching its zenith in March at 339 hours. This steady rise continues, with hours peaking at 344 hours in May, just ahead of the rainy season, illustrating the region's increasing daylight exposure. Even in April, which follows closely with 330 hours, sunlight remains abundant, setting a vibrant backdrop against the backdrop of growing vegetation before the shift to increased rainfall.
As the wet season approaches, sunshine hours remain robust, with a consistent range between 310 and 344 hours from June to October. Notably, June maintains 329 hours of sun despite the onset of precipitation, while the months of July and August offer around 332 hours and 310 hours, respectively. This slight dip in August is followed by a resurgence in sunshine, with September recording 318 hours. The yearly culmination in December brings back a substantial 333 hours, underscoring the cyclical nature of sunlight in Tandjilé, where the interplay between dry and wet seasons influences both the environment and the way of life.
The UV Index in Tandjilé, Chad, indicates an environment with persistently high levels of solar radiation, posing significant health risks associated with sun exposure. Throughout the year, the UV Index typically ranges from 10 to 14, categorizing the exposure as extreme for most months. January marks the onset of this intense radiation, with a UV Index of 11, and February sees an increase to 12. The peak intensity is recorded in August and September, reaching 14, which emphasizes the urgent need for protective measures against skin damage in these months. Remarkably, burn time remains critically low across this period, with just 10 minutes needed for a serious risk of burn.
As the year progresses into the latter months, the UV Index slightly diminishes, with November and December dropping to 10, placing them in the very high category but extending the burn time to 15 minutes. This indicates a minor reprieve in the threat of UV exposure, although caution is still necessary. Overall, the consistently high UV Index levels throughout the year in Tandjilé underscore the importance of implementing sun safety practices, particularly during the peak months of summer, to protect against harmful effects associated with ultraviolet radiation.
