Weather in September
Temperature
September's weather records an average high-temperature of a still moderately hot 28.8°C (83.8°F), showing little deviation from August. In Niangara, the September nights cool down to an average low of 18.5°C (65.3°F).Heat index
Throughout September, the heat index is calculated to be a very hot 36°C (96.8°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
