Weather in August

The arrival of August records an average high-temperature of a still warm 80.6°F (27°C), closely related to the 82.4°F (28°C) observed in July. Williamsville's average low-temperature of 57°F (13.9°C) in August reflects a considerable decline from the daytime peak.Heat index
August's heat index is estimated at 84.2°F (29°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for children. 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.
