Weather in September
Temperature
The beginning of September brings a slight decrease in the average high-temperature, transitioning from a sweltering 95°F (35°C) in August to a hot 88°F (31.1°C). In September, the temperature drops to an average of 68.9°F (20.5°C) at night.Heat index
September's heat index is calculated to be a very hot 98.6°F (37°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating 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. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
