Weather in September
Temperature
In September, the average high-temperature marginally decreases from a hot 86.7°F (30.4°C) in August to a warm 81.1°F (27.3°C). The temperature dips to an average of 59.9°F (15.5°C) during September nights.Heat index
In September, the heat index is estimated at a tropical 86°F (30°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
