Weather in September
Temperature
September denotes a minimal variation in the average high-temperature to a still tropical 30.4°C (86.7°F) from August's 31.1°C (88°F). Gopeng's temperature tends to fall to an average low of 21.5°C (70.7°F) during the nights of September.Heat index
September's heat index is calculated to be a sweltering 38°C (100.4°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', arises from combining readings of air temperature and relative moisture content. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
