Weather in September
Temperature
A minor decrease in the average high-temperature is observed during September, shifting from a tropical 91.8°F (33.2°C) in August to a warm 82.9°F (28.3°C). An average low-temperature of 62.1°F (16.7°C) is observed during the September nights.Heat index
In September, the heat index is calculated to be a tropical 86°F (30°C). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.Heat index determinations are made taking into account the shade and light air movements. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.

The average daily maximum UV index in September is 6. A UV Index value of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for average individuals.Note: The daily maximum UV index of 6 in September interprets into the following advice:
Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
