Heat index

The heat index in January is estimated at a sweltering 39°C (102.2°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
