Weather in September
Temperature
The onset of September brings with it an average high-temperature of a still hot 31.3°C (88.3°F), showing a negligible variation from the month before. During September, Gunung Kaler records a consistent average nighttime temperature of 25°C (77°F).Heat index
For September, the heat index is calculated to be a very hot 39°C (102.2°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Shun overexposure. Protection from sun ravages is indispensable. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
