Weather in June
Temperature
The arrival of June brings a soft temperature shift, with the average high-temperature nudging from a moderately hot 79.5°F (26.4°C) in May to a tropical 88.3°F (31.3°C). Throughout the month of June, Lyman observes a dramatic downturn from the daytime peak temperatures, expecting an average low of 65.8°F (18.8°C).Heat index
June's mean heat index is estimated at a sweltering 100.4°F (38°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
