September weather forecast
Abyei, Sudan

Come September, the rainy season in Abyei is on the decline, both in terms of rainfall amount and frequency. This dip in rainfall signals the advent of the region's dry season. The decline in rainfall is accompanied by an emerging clear sky, paving the way for more sunshine hours. The effect of this change in weather is more pronounced as humidity levels start to decrease, making the atmosphere less thick. Despite the lowering of temperatures compared to August, heat remains a defining element of September’s weather.

Note: The heat index, also known as 'apparent temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
