Weather in September
Temperature
The arrival of September denotes a barely perceptible change in the average high-temperatures to a still tropical 88°F (31.1°C) from August's 91.6°F (33.1°C). During the month of September, the temperature generally drops to a low average of 68.7°F (20.4°C).Heat index
The heat index value for September is appraised at a blisteringly hot 104°F (40°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
