Temperature

December, recognised by an average high temperature of 29.7°C (85.5°F) and a low of 20.4°C (68.7°F), is Guaporema's warmest month.

Heat index

Throughout December, the heat index is computed to be a sweltering 37°C (98.6°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Note: In December, a daily UV index of 6 turns into the following recommendations:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
