Weather in September
Temperature
As September arrives, Bernice's weather displays a minor decrease in high-temperatures, transitioning from August's hot 93.7°F (34.3°C) to a still tropical 88°F (31.1°C). September's average low-temperature reading settles at a comfortable 66.7°F (19.3°C).Heat index
In September, the heat index is appraised at a torrid 100.4°F (38°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Be aware that heat index ratings are designed for shaded locations and minor 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', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
