Weather in January
Temperature
The ushering in of January brings an average high-temperature of a still warm 29.2°C (84.6°F), closely mirroring the 28.9°C (84°F) of December. Hirimbura's nights in January cool down to an average low-temperature of 24°C (75.2°F).Heat index
The heat index for January is estimated at a torrid 35°C (95°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
