Weather in September

The shift into September uncovers an average high-temperature of a still tropical 86.9°F (30.5°C), subtly different from the previous month. The month of September records an average low-temperature of 67.1°F (19.5°C).Heat index
For most parts of September, the heat index is evaluated at a fiery hot 98.6°F (37°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
