Weather in August
Temperature
The average high-temperature during August registers at a still hot 89.6°F (32°C), maintaining a close resemblance to the previous month. Throughout August, the average low-temperature records at an agreeable 70.5°F (21.4°C).Heat index
The heat index in August is calculated to be an extremely hot 104°F (40°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.In terms of the heat index, values are set with light wind and shade conditions in mind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
