Temperature

June's advent denotes a minor fluctuation in the average high-temperature to a hot 91°F (32.8°C) from May's 85.8°F (29.9°C). Houston, during the month of June, experiences an average low-temperature of 75.4°F (24.1°C).

Heat index

June's mean heat index is calculated to be a blistering 111.2°F (44°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.
Heat index details are generally centered around shaded locations and a mild breeze. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
