Weather in June
Temperature
Dennis's transition into June sees a mild rise in the average high-temperature, edging from a warm 79.5°F (26.4°C) in May to a tropical 87.4°F (30.8°C). Dennis, during June, witnesses an average low-temperature of 67.6°F (19.8°C).Heat index
For June, the heat index is estimated at a sweltering 102.2°F (39°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
