Weather in July
Temperature
Black Jack's temperature records reveal July as the warmest month, marked by average highs of 86.4°F (30.2°C) and lows of 67.3°F (19.6°C).Heat index
In July, the average heat index is evaluated at a very hot 100.4°F (38°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Consider that heat index readings are for situations in the shade and light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority.
