Weather in September
Temperature
September brings an average high-temperature of a still very hot 37.8°C (100°F), nearly identical to the preceding month. The nighttime temperature dips to a moderately hot 27.8°C (82°F) on average during September.Heat index
For September, the heat index is appraised at a blisteringly hot 43°C (109.4°F). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.Understanding the heat index involves considering values for shaded locales with light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
