Weather in December
Temperature
The onset of December brings with it an average high-temperature of a still moderately hot 29.6°C (85.3°F), showing a negligible variation from the month before. Jaboatão experiences an average low-temperature of 24.5°C (76.1°F) in the month of December.Heat index
December's average heat index is computed to be a torrid 35°C (95°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
