Weather in August
Temperature
Twelve Hills marks the start of August with an average high-temperature of a still warm 83.8°F (28.8°C), hinting at a slight fluctuation from July's 85.8°F (29.9°C). In the month of August, Twelve Hills records a consistent average low-temperature of 67.3°F (19.6°C).Heat index
August's mean heat index is estimated at a hot 91.4°F (33°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
