Weather in January

January, like December, is another hot summer month in Passo, Brazil, with an average temperature varying between 20.8°C (69.4°F) and 32.3°C (90.1°F).

Temperature

The warmest period is January, when temperatures fluctuate between an average high of 32.3°C (90.1°F) and a low of 20.8°C (69.4°F).

Heat index

For most parts of January, the heat index is evaluated at an extremely hot 41°C (105.8°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
