Weather in September
Temperature
At the onset of September, Batavia records an average high-temperature of a still tropical 31.5°C (88.7°F), showing little deviation from the preceding month. Throughout the month of September, Batavia observes an average nighttime temperature of 24.6°C (76.3°F).Heat index
In September, the heat index is evaluated at a scorching 41°C (105.8°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. As body temperatures escalate without effective heat release, one might face dehydration threats.

Resist overexposure. Safeguarding from solar damage is indispensable. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
