Weather in September
Temperature
September, noted for its average high-temperature of 30.5°C (86.9°F) and an average low-temperature of 21.2°C (70.2°F), is considered the coldest month.Heat index
In September, the average heat index is evaluated at a blisteringly hot 40°C (104°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.One should consider that heat index numbers are for shaded settings and light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
