Weather in September
Temperature
September is marked by an average high-temperature of a still tropical 87.1°F (30.6°C), almost identical to the preceding month. In Shired Island, September is marked by an average low-temperature of 73°F (22.8°C).Heat index
September's average heat index is estimated at a torrid 102.2°F (39°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
