Weather in September
Temperature
As Bohemian welcomes September, the average high-temperature records at a moderately hot 85.1°F (29.5°C), marking an insignificant deviation from the prior month. Maintaining close parity with daytime warmth, the average nocturnal temperature during September stays at a still warm 77.7°F (25.4°C).Heat index
The heat index for September is appraised at a sweltering 95°F (35°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
