Weather in January
Temperature
During January, Biriwa observes a subtle ascent to a still hot 31°C (87.8°F) from December's 30.8°C (87.4°F) in the average high-temperature. During the January nights, an average temperature of 25.3°C (77.5°F) is observed.Heat index
The heat index for January is appraised at a fiery hot 39°C (102.2°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

The months with the highest UV index are January through April, October through December, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV radiation for average individuals.Note: The maximum UV index of 7 during January leads to these instructions:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
