Weather in January
Temperature
January's average high-temperature is a moderately hot 29.7°C (85.5°F), maintaining a close comparison with December's 30.8°C (87.4°F). During the month of January, Cent-Sous anticipates a mean low-temperature of 20.8°C (69.4°F).Heat index
For most parts of January, the heat index is computed to be a very hot 39°C (102.2°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. 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 extremely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
