December weather forecast
Larrakeyah, Australia

December, the first month of the summer in Larrakeyah, is also a hot month, with an average temperature varying between 32.5°C (90.5°F) and 27.8°C (82°F).

Temperature

The initiation of December sees an average high-temperature of a still tropical 32.5°C (90.5°F), showing minor variations from the previous month. The December average low temperature, marginally lower than the daytime high, records at a warm 27.8°C (82°F).

Heat index

December's average heat index is computed to be an extremely hot 43°C (109.4°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.
Factoring in the heat index, values are geared towards shaded areas with light breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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 particularly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Note: In December, the maximum UV index of 7 suggests this advice:
Prevent overexposure. Protection from the sun's harmful effects is needed. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Alert! The Sun's UV rays are heightened by the reflection of sand and water.
