Weather in June
Temperature
June introduces a minor temperature shift, with average high-temperatures adjusting from May's moderately hot 83.3°F (28.5°C) to a hot 90.5°F (32.5°C). Jonestown, during June, witnesses an average low-temperature of 72.1°F (22.3°C).Heat index
June's heat index is calculated to be a blistering 107.6°F (42°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
