Weather in August
Temperature
The arrival of August is marked by an average high-temperature of a still moderately hot 80.6°F (27°C), bearing a close resemblance to July. During the month of August, the temperature in Stanford generally drops to a low average of 63.3°F (17.4°C).Heat index
Throughout August, the heat index is evaluated at a tropical 86°F (30°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. 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 babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
