Weather in August
Temperature
Menlo experiences a transition to a still moderately hot 81°F (27.2°C) in average high-temperatures with the arrival of August, not greatly differing from July's 82.2°F (27.9°C). Throughout August, Menlo experiences a low-temperature average of 62.2°F (16.8°C).Heat index
The heat index for August is evaluated at a tropical 86°F (30°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
