Weather in August

Heat index

August's mean heat index is computed to be a fiery hot 39°C (102.2°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
