Weather in June
Temperature
June's arrival brings a slight change in high-temperatures, adjusting from 74.8°F (23.8°C) in May to a still moderately hot 82.9°F (28.3°C). Jefferson anticipates an average minimum temperature of 63.9°F (17.7°C) in the month of June.Heat index
For June, the heat index is evaluated at a hot 89.6°F (32°C). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. 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.
