Weather in August

In August, the heat index is computed to be a blazing hot 113°F (45°C). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
