Weather in June
Temperature
June's arrival signals an increase in average high-temperatures, moving from May's warm 76.6°F (24.8°C) to a hot 86.5°F (30.3°C). Throughout June, Walnut Grove braces for a considerable drop from daytime highs, with an average low-temperature of 55.8°F (13.2°C).Heat index
In June, the heat index is computed to be a tropical 89.6°F (32°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of 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. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
