Weather in December
Temperature
The beginning of December records an average high-temperature of a still moderately hot 27.4°C (81.3°F), almost echoing the conditions of the previous month. Guaramirim, in December, observes a steady average low-temperature of 18.3°C (64.9°F).Heat index
During December, the heat index is evaluated at a hot 32°C (89.6°F). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
