Weather in September
Temperature
The start of September involves a subtle temperature drop, shifting from a tropical 93°F (33.9°C) in August to a still hot 86.5°F (30.3°C). The average low-temperature, in September, is an enjoyable 65.7°F (18.7°C).Heat index
The heat index in September is computed to be a sweltering 96.8°F (36°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
