Weather in July
Temperature
Heyburn's temperature records reveal July as the warmest month, marked by average highs of 91.4°F (33°C) and lows of 72.1°F (22.3°C).Heat index
July's mean heat index is computed to be a blisteringly hot 109.4°F (43°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
