Weather in August

For most parts of August, the heat index is calculated to be a scorching 107.6°F (42°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Remember that heat index calculations are made for conditions in the shade 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 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
