Weather in August
Temperature
In La Grande, temperatures reach their average annual highs in August, measuring 81.3°F (27.4°C) and a minimum average of 52.2°F (11.2°C).Heat index
The average heat index in August is calculated to be 80.6°F (27°C). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a numerical representation of warmth when taking temperature and moisture levels into account. Elements such as metabolic variations, pregnancy, and physical exertion can influence 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 largely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
