Weather in September
Temperature
As August transitions into September, Reddochs records an average high-temperature of a still hot 87.3°F (30.7°C), showing a gentle shift from the preceding month. Throughout September nights, Reddochs registers an average low-temperature of 67.3°F (19.6°C).Heat index
The heat index for September is calculated to be a torrid 100.4°F (38°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
