Weather in July
Temperature
Defiance's temperatures tend to reach their peak averages in July, with a high of 85.3°F (29.6°C) and a low of 63°F (17.2°C).Heat index
During July, the heat index is estimated at a sweltering 96.8°F (36°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
