Weather in September
Temperature
Transitioning from August to September, Insmore observes an average high-temperature of a still hot 88.2°F (31.2°C), differing subtly from the previous month. In September, the average low-temperature is an enjoyable 67.6°F (19.8°C).Heat index
During September, the heat index is appraised at a torrid 102.2°F (39°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
