Weather in September
Temperature
The ushering in of September brings an average high-temperature of a still hot 86.2°F (30.1°C), closely mirroring the 89.2°F (31.8°C) of August. Braithwaite records an average low-temperature of 76.6°F (24.8°C) throughout the month of September.Heat index
In September, the average heat index is evaluated at a torrid 96.8°F (36°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
