Weather in September
Temperature
September notes an average high-temperature of a still hot 88.3°F (31.3°C), subtly differing from August's 90.7°F (32.6°C). Skytop's average low-temperature during September nights is observed to be a warm 73.4°F (23°C).Heat index
Throughout September, the heat index is estimated at a blistering 105.8°F (41°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. 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 hold particular importance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Rising body temperatures due to excess heat retention could signify impending heat disorders.
