Weather in August
Temperature
During August, Richfield Heights records an average high-temperature of a still warm 83.1°F (28.4°C), marking a slight divergence from July's 84.7°F (29.3°C). Richfield Heights registers a significant drop in temperature in August, with average nighttime lows of 61°F (16.1°C).Heat index
For most parts of August, the heat index is estimated at a tropical 86°F (30°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
