Weather in August
Temperature
The arrival of August sees an average high-temperature of a still hot 91.4°F (33°C), hardly diverging from July's 91.9°F (33.3°C). During August nights, Mannassa records an average temperature of 71.8°F (22.1°C).Heat index
Throughout August, the heat index is appraised at a life-threatening hot 113°F (45°C). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.Heat index determinations are made taking into account the shade and light air movements. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. As body temperatures escalate without effective heat release, one might face dehydration threats.
