Weather in September

The shift from August to September includes a small decrease in the average high-temperature, from a hot 89.8°F (32.1°C) to a warm 83.1°F (28.4°C). The temperature notes a substantial fall from the daily peak to an average of 61.2°F (16.2°C) during September nights.Heat index
September's mean heat index is evaluated at 82.4°F (28°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
