Weather in August
Temperature
During August, Sperry observes a subtle ascent to a still moderately hot 81.7°F (27.6°C) from July's 82.4°F (28°C) in the average high-temperature. An average nighttime temperature of 63.3°F (17.4°C) is witnessed throughout August.Heat index
August's mean heat index is computed to be a hot 87.8°F (31°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. 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 'real feel', is found by incorporating humidity levels into the air temperature measurement. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
