Weather in June
Temperature
The start of June brings a shift in the average high-temperature, increasing from May's moderately hot 78.4°F (25.8°C) to a tropical 88.7°F (31.5°C). Lewisville's nights in June cool down to an average low-temperature of 68.9°F (20.5°C).Heat index
For most parts of June, the heat index is evaluated at an extremely hot 104°F (40°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
