Weather in September
Temperature
Lunenburg's progression into September involves a minor drop in the average high-temperature, slightly receding from a tropical 87.4°F (30.8°C) in August to a warm 80.8°F (27.1°C). Throughout the month of September, Lunenburg sees a steady low-temperature average of 61.7°F (16.5°C).Heat index
September's heat index is computed to be 84.2°F (29°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
