Weather in June
Temperature
The arrival of June sees a shift in the average high-temperature, moving from a warm 79.2°F (26.2°C) in May to a tropical 88.3°F (31.3°C). During the nights in June, an average low-temperature of 67.6°F (19.8°C) is observed in Mount Vernon.Heat index
The heat index value during June is evaluated at a scorching 104°F (40°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Realize that the values for the heat index are set for shaded places and light winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance 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.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
