Weather in January
Temperature
The arrival of January brings an average high-temperature of a moderately hot 29.7°C (85.5°F), subtly diverging from December's 30.5°C (86.9°F). Arjawinangun temperatures generally rest at a low of 24.3°C (75.7°F) during the January nights.Heat index
The heat index for January is computed to be a torrid 36°C (96.8°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Heat index details are generally centered around shaded locations and a mild breeze. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Rising body temperatures due to excess heat retention could signify impending heat disorders.
