Weather in September
Temperature
Vattmannville observes a small decrease in the average high-temperature with the arrival of September, falling from August's fiery hot 95.9°F (35.5°C) to a hot 90.3°F (32.4°C). Nighttime temperature dips to a mean of 76.3°F (24.6°C) during September.Heat index
The heat index for September is computed to be a blisteringly hot 107.6°F (42°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', arises from combining readings of air temperature and relative moisture content. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
