Weather in December
Temperature
Stuart Park experiences an average high-temperature of a still tropical 32.5°C (90.5°F) with the onset of December, subtly varied from November's 33.3°C (91.9°F). Night temperatures during December stabilize at an average of 27.8°C (82°F), closely mirroring the daytime temperatures.Heat index
December's mean heat index is appraised at a blisteringly hot 43°C (109.4°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.

A UV Index of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for average individuals.Note: The maximum UV index of 7 during December leads to these instructions:
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. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation. Take heed! Reflections of sand and water make the Sun's UV rays stronger.
