Weather in August

Post greets August with an average high-temperature of a still moderately hot 80.6°F (27°C), marking a slight deviation from the preceding month. The temperature notes a substantial fall from the daily peak to an average of 54.3°F (12.4°C) during August nights.Heat index
August's mean heat index is appraised at 80.6°F (27°C). Exhaustion is likely with prolonged exposure and activity. Sustaining activity may result in heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
