Weather in September
Temperature
The start of September signals a gentle decrease in the average high-temperature, transitioning from a hot 92.5°F (33.6°C) in August to a still tropical 86.4°F (30.2°C). Shawmut cools down to an average low-temperature of 64.9°F (18.3°C) throughout the month of September.Heat index
September's mean heat index is calculated to be a fiery hot 96.8°F (36°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. 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 quite important for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Limit exposure to direct sunlight during these hours. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes. Take heed! Reflection from the snow can almost amplify the Sun's UV radiation by double.
