Weather in September
Temperature
September ushers in a minute temperature change, with average high-temperatures reducing from August's torrid 99.3°F (37.4°C) to a hot 91.4°F (33°C). In the month of September, the nighttime temperature dips to a steady average of 74.8°F (23.8°C).Heat index
September's heat index is evaluated at a blisteringly hot 104°F (40°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Note that heat index values are valued for light wind and location in the shade. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. 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. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
