Weather in December
Temperature
The warmest month is December, with an average high-temperature of 29.7°C (85.5°F) and an average low-temperature of 20.4°C (68.7°F).Heat index
The heat index value during December is calculated to be a very hot 37°C (98.6°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
