Weather in August
Temperature
August's advent denotes a minor fluctuation in the average high-temperature to a still moderately hot 80.6°F (27°C) from July's 82°F (27.8°C). Harrisburg experiences an average low-temperature reading of 62.2°F (16.8°C) throughout August.Heat index
The average heat index in August is appraised at a hot 86°F (30°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Note that heat index values are valued for light wind and location in the shade. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
