Weather in September
Temperature

September's average heat index is appraised at an extremely hot 105.8°F (41°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. 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 are quite important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
