Weather in June
Temperature
June's onset is marked by a temperature increase, moving from a moderately hot 77.9°F (25.5°C) in May to a hot 88.2°F (31.2°C). Knoxville measures a considerable dip from daytime highs with an average low-temperature of 65.8°F (18.8°C) during June.Heat index
The heat index for June is estimated at a fiery hot 102.2°F (39°C). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.The heat index's values are generally associated with conditions in shade and light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
