Weather in August
Temperature
The advent of August sees the average high-temperature at a still tropical 88.3°F (31.3°C), subtly shifted from July's 90.7°F (32.6°C). During the month of August, Chester's nighttime temperature lowers to an average of 68.9°F (20.5°C).Heat index
The heat index value for August is estimated at a very hot 102.2°F (39°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Stay clear of intense sun exposure. Solar protection is of utmost significance. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
