Weather in September
Temperature
The arrival of September records an average high-temperature of a hot 30.6°C (87.1°F), closely related to the 29.9°C (85.8°F) observed in August. In the month of September, Sarajaya witnesses a consistent average low-temperature of 22.6°C (72.7°F).Heat index
Throughout September, the heat index is estimated at a fiery hot 37°C (98.6°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
