Weather in August
Temperature
Discovery Bay experiences a transition to a still tropical 87.4°F (30.8°C) in average high-temperatures with the arrival of August, not greatly differing from July's 88.5°F (31.4°C). Discovery Bay in August observes a substantial swing from the daily highs, with average nighttime temperatures of 57.4°F (14.1°C).Heat index
August's mean heat index is evaluated at a hot 93.2°F (34°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
