Weather in August

August, the last month of the summer in Oakdale, is another torrid month, with an average temperature fluctuating between 95.5°F (35.3°C) and 61.3°F (16.3°C).

Temperature

Oakdale experiences a transition to a still very hot 95.5°F (35.3°C) in average high-temperatures with the arrival of August, not greatly differing from July's 96.4°F (35.8°C). Oakdale demonstrates a significant disparity from daytime highs throughout the month of August, with an average nighttime temperature of 61.3°F (16.3°C).

Heat index

August's average heat index is estimated at a torrid 100.4°F (38°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
