January weather forecast
Arês, Brazil

January, like December, is another tropical summer month in Arês, Brazil, with an average temperature ranging between max 30.4°C (86.7°F) and min 25.5°C (77.9°F).

Temperature

During January, the average high-temperature is a still tropical 30.4°C (86.7°F), maintaining a close resemblance to that of the preceding month. January nights reflect a consistent temperature dip to a warm 25.5°C (77.9°F), a slight descent from daytime peaks.

Heat index

The heat index value for January is estimated at a torrid 37°C (98.6°F). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Note: The UV index of 7 during January leads to these advisories:
Guard oneself from overexposure. Defence against sun injury is vital. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
