Weather in August
Temperature
The advent of August sees the average high-temperature at a warm 85.3°F (29.6°C), subtly shifted from July's 86.7°F (30.4°C). In August, the temperature registers a significant dip to an average of 61°F (16.1°C) at night.Heat index
In August, the heat index is estimated at a fiery hot 95°F (35°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Observations indicate that the heat index values are for shady locations with light wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
