Weather in December
Temperature
The onset of December marks an average high-temperature of a still moderately hot 29°C (84.2°F), hardly differing from November's 26.3°C (79.3°F). During December, Santa Cruz do Sul's temperature falls to a steady low-temperature average of 17.8°C (64°F).Heat index
Throughout December, the heat index is calculated to be a hot 34°C (93.2°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
