Weather in September
Temperature
As August shifts into September, a minor alteration in temperatures is observed, with average highs reducing from a tropical 90.1°F (32.3°C) to a warm 83.7°F (28.7°C). The average low-temperature during September nights is a refreshing 63°F (17.2°C).Heat index
September's heat index is computed to be a tropical 91.4°F (33°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
