Heat index

January's average heat index is computed to be an extremely hot 40°C (104°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
