Weather in August
Temperature
At the onset of August, Donner records an average high-temperature of a still tropical 89.2°F (31.8°C), showing little deviation from the preceding month. The nighttime temperature, during August, averages of 75.7°F (24.3°C).Heat index
For August, the heat index is calculated to be an extremely hot 109.4°F (43°C). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.Realize that the values for the heat index are set for shaded places and light winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance 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 body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
