Weather in January
Temperature
The arrival of January brings an average high-temperature of a hot 30.3°C (86.5°F), subtly diverging from December's 29.7°C (85.5°F). In Bombuwala, in January, the average low-temperature is a moderately hot 23.4°C (74.1°F).Heat index
The heat index for January is computed to be a fiery hot 37°C (98.6°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
