Weather in June
Temperature
A rise in the average high-temperature is observed during June, moving from a warm 76.1°F (24.5°C) in May to a still moderately hot 85.3°F (29.6°C). Nighttime temperatures in Rockwood hover around an average low of 66°F (18.9°C) in June.Heat index
The heat index value during June is calculated to be a fiery hot 95°F (35°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. 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 'feels like' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly critical for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
