Weather in September
Temperature
Nangola starts September with an average high-temperature of a still tropical 34.9°C (94.8°F), a minor shift from August's 33°C (91.4°F). Nangola's average low-temperature for the month of September records at a moderately hot 24.7°C (76.5°F).Heat index
During September, the heat index is estimated at a life-threatening hot 45°C (113°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
