Weather in August
Temperature

In August, the average heat index is evaluated at a burning hot 113°F (45°C). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
