Weather in September
Temperature
Turnbull's shift from August to September is accompanied by an average high-temperature of a still tropical 88°F (31.1°C), a slight deviation from 91.9°F (33.3°C). Turnbull records an average low of 68°F (20°C) throughout the nights in September.Heat index
The heat index value for September is estimated at a very hot 102.2°F (39°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. 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 primarily vital for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
