Weather in September
Temperature
With the commencement of September, Hammondville records a moderate temperature decline, with the average high easing from August's hot 86.4°F (30.2°C) to a warm 81°F (27.2°C). Hammondville experiences a consistent average temperature of 61.3°F (16.3°C) throughout the nights in September.Heat index
The heat index value during September is computed to be a hot 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
