Weather in August

August, the last month of the summer in Eugene, is another tropical month, with an average temperature ranging between max 87.1°F (30.6°C) and min 65.7°F (18.7°C).

Temperature

August experiences an average high-temperature of a still tropical 87.1°F (30.6°C), barely different from July's 88.9°F (31.6°C). An average minimum temperature of 65.7°F (18.7°C) is recorded during the month of August.

Heat index

August's mean heat index is evaluated at a sweltering 98.6°F (37°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
