Weather in September
Temperature
In the transition to September, Delight observes a minor drop in the average high-temperature, shifting from 92.5°F (33.6°C) in August to a still tropical 86.4°F (30.2°C). Delight, in September, experiences an average temperature of 64.9°F (18.3°C) at night.Heat index
The heat index value for September is evaluated at a very hot 96.8°F (36°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes. Consider carefully! The reflective quality of snow can almost double the intensity of the Sun's UV radiation.
