Heat index

During December, the heat index is computed to be a blisteringly hot 40°C (104°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Factoring in the heat index, values are geared towards shaded areas with light breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

The average relative humidity in December is 76%.
