Weather in June
Temperature
The start of June is characterized by a subtle increase in the average high-temperature, transitioning from a warm 81.1°F (27.3°C) in May to a hot 88.2°F (31.2°C). Throughout June, Barnwell experiences a low-temperature average of 70.7°F (21.5°C).Heat index
The heat index value for June is computed to be a very hot 102.2°F (39°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Observations indicate that the heat index values are for shady locations with light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
