Weather in January

January, the same as December, is a moderately hot summer month in Nova Aliança, Brazil, with an average temperature ranging between max 29°C (84.2°F) and min 20.7°C (69.3°F).

Temperature

January's beginning signals an average high-temperature of a still moderately hot 29°C (84.2°F), barely different from December's 29.8°C (85.6°F). During January, Nova Aliança experiences an average low-temperature of 20.7°C (69.3°F) at night.

Heat index

The heat index in January is estimated at a torrid 36°C (96.8°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

UV index

The months with the highest UV index are January, March through December, with an average maximum UV index of 6. A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for the ordinary person.
Note: A maximum high UV index of 6 in January translates into the following recommendations:
Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
