Weather in August
Temperature
August's weather displays an average high-temperature of a still warm 82.9°F (28.3°C), slightly varied from July's 85.3°F (29.6°C). Throughout the month of August, the nighttime temperature in Berwyn, Pennsylvania, dips to an average of 66°F (18.9°C).Heat index
Throughout August, the heat index is evaluated at a hot 89.6°F (32°C). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
