Weather in August
Temperature
Arroyo Grande marks the onset of August with an average high-temperature of a still tropical 87.4°F, subtly divergent from July's 88°F. In Arroyo Grande, the nocturnal temperatures throughout August show a marginal dip from the daytime averages, settling at a moderately hot 80.2°F.Heat index
During August, the heat index is computed to be a scorching 104°F. Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Shield from overexposure. Defense against sun-related harm is required. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
