Weather in September
Temperature
The transition into September reveals an average high-temperature of a still hot 32.7°C (90.9°F), mirroring a close resemblance to August. Throughout September, an average low-temperature of 21.1°C (70°F) is experienced in Gengwa.Heat index
The heat index value for September is evaluated at a blistering 44°C (111.2°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.Evaluating the heat index requires understanding its values in the shade and with gentle winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
