Weather in August

The transition from July to August sees an average high-temperature of a still warm 81.3°F (27.4°C), indicating a minor variance from the prior month. Throughout the month of August, Williamstown witnesses an average temperature of 63.1°F (17.3°C).Heat index
The heat index value during August is computed to be a hot 87.8°F (31°C). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
