Weather in August
Temperature
Henley registers an average high-temperature of a warm 84.9°F (29.4°C) with the arrival of August, showing minor deviation from the preceding month. The average low-temperature reading in August for Henley reflects a significant fall from the daytime highs, stabilizing at a refreshing 62.1°F (16.7°C).Heat index
The average heat index in August is computed to be a torrid 95°F (35°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
