Weather in August
Temperature
In August, Chester's weather conditions record an average high-temperature of a still tropical 91°F (32.8°C), demonstrating little divergence from the preceding month. August nights experience a distinct temperature drop from the daily highs, with an average low-temperature of 68.7°F (20.4°C).Heat index
The heat index in August is computed to be a scorching 109.4°F (43°C). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
