Weather in September
Temperature
With September's arrival, Holder notes an average high-temperature of a still tropical 88.2°F (31.2°C), closely following the trend of the preceding month. Holder, in September, observes a steady average low-temperature of 72.9°F (22.7°C).Heat index
In September, the heat index is computed to be a blisteringly hot 105.8°F (41°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 are extremely significant for babies and toddlers. 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.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
