Weather in August

The last month of the summer, August, is also a fiery hot month in Eugene, California, with an average temperature ranging between min 61.3°F (16.3°C) and max 95.5°F (35.3°C).

Temperature

August's onset records a minor alteration in the average high-temperature to a still sweltering 95.5°F (35.3°C) from July's 96.4°F (35.8°C). In the face of high daytime temperatures, Eugene witnesses a consistent average nighttime low of 61.3°F (16.3°C) during August.

Heat index

The heat index value for August is estimated at a very hot 100.4°F (38°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
