Weather in July
Temperature
In Chesterfield, July records the highest average temperatures, peaking at 90.7°F (32.6°C) and reaching a low of 70.3°F (21.3°C).Heat index
For July, the heat index is evaluated at a blistering 105.8°F (41°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
