Weather in January
Temperature
The shift from December to January is characterized by an average high-temperature of a still tropical 30.5°C (86.9°F), not significantly different from the 30.8°C (87.4°F) of December. During the month of January, Visiga experiences a steady low-temperature average of 25.3°C (77.5°F).Heat index
The average heat index in January is calculated to be a sweltering 39°C (102.2°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. 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. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

A UV Index of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for ordinary individuals.Note: The maximum UV index of 7 during January leads to these instructions:
Inhibit overexposure. Warding off sun damage is of utmost importance. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
