Weather in December
Temperature
January and December, with an average high-temperature of 30.9°C (87.6°F), are marked as the warmest months.Heat index
During December, the heat index is computed to be a sweltering 37°C (98.6°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. 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 particularly relevant to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

The month with the most rainfall is December, when the rain falls for 14.6 days and typically aggregates up to 70mm (2.76") of precipitation.Daylight

A UV Index value of 6 to 7 symbolizes a high threat to health from unprotected exposure to Sun's UV rays for ordinary individuals.Note: The daily high UV index of 6 in December translates into this advice:
Guard against overexposure. Protection from sun-induced harm is essential. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
