Weather in July
Temperature
Cresthill's warmest weather arrives in July, when temperatures average a high of 87.6°F (30.9°C) and a low of 65.8°F (18.8°C).Heat index
The average heat index in July is estimated at a fiery hot 100.4°F (38°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.One should consider that heat index numbers are for shaded settings and light wind. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
