Temperature

As December begins, there's a slight increase in the average high-temperature, moving from a warm 28.5°C (83.3°F) in November to a hot 31.7°C (89.1°F). In stark contrast to the day's heat, the temperature dips to an average of 17.8°C (64°F) during December nights.

Heat index

Throughout December, the heat index is calculated to be a very hot 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
