Temperature

The unfolding of July shows an average high-temperature of a still tropical 93.9°F (34.4°C), indicating a slight variance from June's 89.6°F (32°C). McKinney records an average low-temperature of 75°F (23.9°C) throughout the month of July.

Heat index

Throughout July, the heat index is appraised at a burning hot 113°F (45°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
