Weather in August
Temperature
The start of August marks an average high-temperature of a still moderately hot 81.1°F (27.3°C), hardly distinguishable from the conditions in July. Sierra City experiences a significant downturn from peak daytime temperatures throughout August, with the average low-temperature dipping to a chilly 46°F (7.8°C).Heat index
The average heat index in August is computed to be 80.6°F (27°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Note that heat index values are valued for light wind and location in the shade. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
