Weather in June
Temperature
The onset of June marks a slight increase in the average high-temperature, moving from 74.8°F (23.8°C) in May to a still moderately hot 82.9°F (28.3°C). In Jefferson, an average nighttime temperature of 63.9°F (17.7°C) is expected during June.Heat index
During June, the heat index is computed to be a hot 89.6°F (32°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 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.
