Weather in September
Temperature
The dawn of September sees an average high-temperature of a tropical 30.2°C (86.4°F), subtly contrasting with August's 29.6°C (85.3°F). Kasepuhan experiences an average low-temperature reading of 23.8°C (74.8°F) throughout September.Heat index
In September, the heat index is estimated at a torrid 36°C (96.8°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
