September weather forecast
Lidah Kulon, Indonesia

September, the first month of the spring in Lidah Kulon, is still a tropical month, with an average temperature varying between 24.4°C (75.9°F) and 31.7°C (89.1°F).

Temperature

The initiation of September records an average high-temperature of a still tropical 31.7°C (89.1°F), displaying a near consistency with the previous month. During September, the average low-temperature is recorded at a moderately hot 24.4°C (75.9°F).

Heat index

The average heat index in September is estimated at a sweltering 38°C (100.4°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
Observations indicate that the heat index values are for shady locations with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Guard against overexposure. Protection from sun-induced harm is essential. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
