Weather in July
Temperature
July stands out as Dayton's warmest month, with an average high-temperature of 81.3°F (27.4°C) and a low-temperature of 64.9°F (18.3°C).Heat index
July's average heat index is calculated to be a tropical 87.8°F (31°C). Extended exposure and activity might lead to tiredness, potentially resulting in heat cramps.The heat index's values are generally associated with conditions in shade and light breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
