Weather in July
Temperature
Dayton witnesses the warmest weather in July, with temperatures averaging a high of 81.1°F (27.3°C) and a low of 64°F (17.8°C).Heat index
The heat index in July is computed to be a hot 87.8°F (31°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Understand that the heat index values take into account shaded locations and mild winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. 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 are highly critical for babies and toddlers. 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.
