Weather in July

July in Festus, Missouri, is a tropical summer month, with temperature in the range of an average high of 88°F (31.1°C) and an average low of 68.2°F (20.1°C).

Temperature

July, with its average high-temperature of 88°F (31.1°C) and an average low-temperature of 68.2°F (20.1°C), holds the record as the warmest month.

Heat index

July's heat index is calculated to be a blistering 104°F (40°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Heat index details are generally centered around shaded locations and a mild breeze. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. 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 normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Boost your sun resistance with garments that are densely woven yet spacious.
