Heat index

The heat index value during June is computed to be a blistering 41°C (105.8°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

In June, the average relative humidity is 73%.
