Weather in January
Temperature
Três Fronteiras's entry into January measures an average high-temperature of a warm 29.6°C (85.3°F), closely parallel to the preceding month. During the month of January, an average low-temperature of 21.6°C (70.9°F) is recorded.Heat index
Throughout January, the heat index is evaluated at a torrid 37°C (98.6°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for the average person.Note: In January, a regular UV index of 6 translates into these guidelines:
Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
