Weather in August
Temperature
The commencement of August notes an average high-temperature of a still hot 90.3°F (32.4°C), exhibiting little difference from the previous month. During August, the temperature is averaged to a low of 72.1°F (22.3°C) at night.Heat index
Throughout August, the heat index is calculated to be a burning hot 113°F (45°C). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
