Weather in August
Temperature
Shaniko's shift from July to August is accompanied by an average high-temperature of a still warm 81.7°F (27.6°C), a slight deviation from 82°F (27.8°C). A notable decrease from the day's highest temperature marks August, culminating in an average low of 54°F (12.2°C).Heat index
The heat index in August is estimated at 82.4°F (28°C). Long-lasting exposure and activity potentially induce a sense of weariness, with the risk of heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. 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', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 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.
