Weather in September
Temperature
September's arrival coincides with a soft drop in the average high-temperature, subtly decreasing from August's tropical 87.3°F (30.7°C) to a warm 81.5°F (27.5°C). An average nighttime temperature of 60.8°F (16°C) is noted during the month of September.Heat index

Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids frequently fail to realize the necessity for resting and hydrating.
