June brings a temperature change, with average high-temperatures moving from May's warm 82.2°F (27.9°C) to a tropical 91.2°F (32.9°C). Grapevine observes an average low-temperature of 73.9°F (23.3°C) during June nights.

Heat index

Always consider that heat index estimations are for light winds and places in the shade. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for 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.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
