Weather in August
Temperature
Upon the beginning of August, Riverside's high-temperatures register at a warm 84.7°F (29.3°C), closely mirroring the preceding month. The average temperature during August nights dips to an enjoyable 66.2°F (19°C).Heat index
August's heat index is calculated to be a fiery hot 95°F (35°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.For clarity, heat index numbers account for light winds and areas under shade. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
