Weather in August
Temperature
With the start of August, Black Jack measures an average high-temperature of a moderately hot 85.3°F (29.6°C), not significantly differing from July's 86.5°F (30.3°C). Throughout the month of August, Black Jack witnesses an average temperature of 66.7°F (19.3°C).Heat index
The heat index value during August is computed to be a sweltering 95°F (35°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', determines the feeling of heat when you account for the relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Sunshine

The months with the highest UV index are May through August, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for the average person.Note: A daily high UV index of 6 in August leads to these guidelines:
Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
