Weather in September
Temperature
A change in temperatures is noted as August gives way to September, with average highs reducing from a fiery hot 95.5°F (35.3°C) to a hot 86.2°F (30.1°C). In September, the recorded average low-temperature is an enjoyable 67.1°F (19.5°C).Heat index
In September, the average heat index is computed to be a hot 91.4°F (33°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
