Weather in August
Temperature
Chesterfield experiences a subtle adjustment in high-temperatures to a still tropical 88.3°F (31.3°C) with the onset of August, maintaining near parity with July's 90.7°F (32.6°C). During August, the temperature tends to dip to an average of 68.9°F (20.5°C) at night.Heat index
August's average heat index is evaluated at a torrid 102.2°F (39°C). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Stay clear of intense sun exposure. Solar protection is of utmost significance. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
