Weather in September
Temperature
The arrival of September is marked by an average high-temperature of a moderately hot 29.2°C (84.6°F), bearing a close resemblance to August. The month of September records an average low-temperature of 22.1°C (71.8°F) in Salcoatitan.Heat index
September's heat index is estimated at a very hot 36°C (96.8°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Know that the heat index computations account for shaded terrains and slight winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. 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 natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
