Weather in September
Temperature
The transition into September shows a subtle variation to a moderately hot 82.9°F (28.3°C) from August's 87.6°F (30.9°C) in the average high-temperature. September sees the temperature falling to a mean low of 62.6°F (17°C).Heat index
The heat index value during September is evaluated at a tropical 89.6°F (32°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. 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', ties air temperature with relative humidity to produce the perceived temperature sensation. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
