Temperature

Heat index

August's mean heat index is evaluated at a fiery hot 100.4°F (38°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
