Weather in September
Temperature
The beginning of September reveals an average high-temperature of a still hot 87.4°F (30.8°C), showing minimal deviation from the previous month. An average low-temperature of 67.1°F (19.5°C) is observed during the September nights.Heat index
September's average heat index is calculated to be a very hot 100.4°F (38°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
