Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a torrid 95.2°F (35.1°C) in August to a tropical 87.1°F (30.6°C). Sheffield temperatures generally rest at a low of 69.6°F (20.9°C) during the September nights.Heat index
September's mean heat index is evaluated at a hot 89.6°F (32°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
