Weather in September
Temperature
The shift from August to September coincides with a small decrease in the average high-temperature, down to a still hot 87.3°F (30.7°C) from 93.7°F (34.3°C). Contrasted against daytime highs, Haworth records an average nighttime low of 65.7°F (18.7°C) in September.Heat index
September's heat index is evaluated at a very hot 96.8°F (36°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
