Weather in September
Temperature
The commencement of September introduces an average high-temperature of a still tropical 87.1°F (30.6°C), closely mirroring the preceding month. An average low-temperature of 67.3°F (19.6°C) marks the month of September.Heat index
The average heat index in September is evaluated at a torrid 98.6°F (37°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital 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.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Take precautions against overexposure. Protection against sun damage is needed. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
