Temperature

The arrival of January coincides with an average high-temperature of a moderately hot 29.8°C (85.6°F), indicating a minimal shift from December's 30.2°C (86.4°F). Throughout January nights, Bereina experiences a consistent temperature average of 24.4°C (75.9°F).

Heat index

In January, the average heat index is calculated to be a torrid 35°C (95°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

UV index

The months with the highest UV index in Bereina are January, March through May, October through December, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for the average person.
Note: A maximum UV index of 7 in January translates into the following recommendations:
Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
