Weather in August

The last month of the summer, August, is a sweltering month in Washington, Texas, with an average temperature fluctuating between 74.8°F (23.8°C) and 95.5°F (35.3°C).

Temperature

August, with its average high-temperature of 95.5°F (35.3°C) and an average low-temperature of 74.8°F (23.8°C), holds the record as the warmest month.

Heat index

August's average heat index is estimated at a burning hot 122°F (50°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
