January weather forecast
Barro Duro, Brazil

January, the same as December, in Barro Duro, Brazil, is another hot summer month, with temperature in the range of an average low of 22.9°C (73.2°F) and an average high of 31.8°C (89.2°F).

Temperature

January begins with an average high-temperature of a still tropical 31.8°C (89.2°F), reflecting close similarity to the preceding month. Throughout the month of January, the nighttime temperature dips to an average of 22.9°C (73.2°F).

Heat index

For most parts of January, the heat index is evaluated at a blisteringly hot 42°C (107.6°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Note: The maximum daily UV index of 7 in January interprets into the following recommendations:
Deflect overexposure. Sun protection is a necessity. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. 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.
