Weather in December
Temperature

In December, the heat index is calculated to be a torrid 39°C (102.2°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
