Weather in December
Temperature
Maracanaú's weather in December indicates an average high-temperature of a still tropical 31.3°C (88.3°F), nearly consistent with the 31.5°C (88.7°F) of November. The average low-temperature, in December, is a warm 25°C (77°F).Heat index
The heat index value for December is appraised at a fiery hot 39°C (102.2°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Realize that the values for the heat index are set for shaded places and light winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
