Weather in January
Temperature
The arrival of January sees an average high-temperature of a still hot 31°C (87.8°F), hardly diverging from December's 30.6°C (87.1°F). Throughout the month of January, Setapak witnesses an average temperature of 22.3°C (72.1°F).Heat index
January's mean heat index is evaluated at a blisteringly hot 41°C (105.8°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.In reference to the heat index, it's for places in shade and with a slight wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
