Weather in December

December, the first month of the winter in Five Star, is also a moderately hot month, with an average temperature fluctuating between 23.4°C (74.1°F) and 29°C (84.2°F).

Temperature

The transition into December notes an average high-temperature of a warm 29°C (84.2°F), revealing a mild distinction from the 30.1°C (86.2°F) in November. Five Star experiences a consistent average temperature of 23.4°C (74.1°F) throughout the nights in December.

Heat index

The heat index value during December is calculated to be a fiery hot 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Humidity

July and December, with an average relative humidity of 83%, are the most humid months.

Rainfall

In Five Star, during December, the rain falls for 27.4 days and regularly aggregates up to 150mm (5.91") of precipitation. Throughout the year, there are 305.1 rainfall days, and 1386mm (54.57") of precipitation is accumulated.

Sunshine

December has the least sunshine of the year, with an average of 6.4h of sunshine.

UV index

The months with the lowest UV index are January, February, November and December, with an average maximum UV index of 6. A UV Index of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for the ordinary person.
Note: During December, 6 as the daily maximum UV index converts into the following advice:
Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
