Weather in June
Temperature
The shift from May to June brings an increase in the average high-temperature, moving from 75.7°F (24.3°C) to a still moderately hot 85.6°F (29.8°C). Jonesboro experiences an average temperature drop to an enjoyable 66.2°F (19°C) during June nights.Heat index
The average heat index in June is evaluated at a fiery hot 96.8°F (36°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Consider that heat index readings are for situations in the shade and light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
