Temperature

December is marked by an average high-temperature of a still hot 31.7°C (89.1°F), almost identical to the preceding month. An average low-temperature of 21.3°C (70.3°F) is expected during December.

Heat index

December's heat index is calculated to be a blisteringly hot 44°C (111.2°F). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.
When assessing, remember that heat index measurements are for light winds and shaded spots. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
