Weather in June
Temperature
June sees a temperature increase, moving from a warm 78.3°F (25.7°C) in May to a tropical 91°F (32.8°C). Jefferson encounters an average low-temperature of 71.2°F (21.8°C) during June nights.Heat index
The heat index value for June is calculated to be a fiery hot 102.2°F (39°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.One should consider that heat index numbers are for shaded settings and light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
