Weather in September
Temperature
Ciawijapura's transition from August to September introduces an average high-temperature of a tropical 30.6°C (87.1°F), marking an insignificant variation from the 29.9°C (85.8°F). In Ciawijapura, the average nighttime temperature during September is an agreeable 22.6°C (72.7°F).Heat index
Throughout September, the heat index is calculated to be a fiery hot 37°C (98.6°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
