Weather in June
Temperature
With the onset of June, Jefferson's average high-temperature experiences a slight rise, moving from May's warm 84°F (28.9°C) to a tropical 91.2°F (32.9°C). Jefferson reports an average low-temperature of 70°F (21.1°C) during the nights of June.Heat index
During June, the heat index is computed to be a blistering 111.2°F (44°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. 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. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
