Weather in December
Temperature
The transition into December in Parys shows a subtle variation to a still warm 28.5°C (83.3°F) from November's 28°C (82.4°F) in the average high-temperature. Throughout December, Parys records an average temperature of 16.8°C (62.2°F) at night.Heat index
December's mean heat index is calculated to be 29°C (84.2°F). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
