The first month of the summer, December, is still a warm month in Monte Aprazível, Brazil, with an average temperature varying between 29.8°C (85.6°F) and 21.2°C (70.2°F).

Temperature

The beginning of December records an average high-temperature of a warm 29.8°C (85.6°F), marking a negligible difference from November's 30°C (86°F). Throughout the month of December, the average temperature dips to an agreeable 21.2°C (70.2°F) at night.

Heat index

December's heat index is computed to be a sweltering 37°C (98.6°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
