Weather in September
Temperature
The arrival of September is marked by a minor reduction in average high-temperature, sliding from 93.4°F (34.1°C) in August to a still hot 87.4°F (30.8°C). Lamberton usually reports an average low-temperature of 66°F (18.9°C) during the month of September.Heat index
September's average heat index is computed to be a sweltering 98.6°F (37°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
