Weather in August
Temperature
August experiences an average high-temperature of a still moderately hot 81.3°F (27.4°C), barely different from July's 83.8°F (28.8°C). Throughout the month of August, McSherrystown witnesses an average temperature of 62.8°F (17.1°C).Heat index
For most parts of August, the heat index is computed to be a tropical 86°F (30°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
