Weather in September
Temperature
The shift from August to September coincides with a small decrease in the average high-temperature, down to a still tropical 88.2°F (31.2°C) from 93.9°F (34.4°C). The average temperature drops to a pleasant 72.7°F (22.6°C) during the night in the month of September.Heat index
The heat index value for September is calculated to be a blistering 104°F (40°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.The heat index's values are generally associated with conditions in shade and light breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
