Weather in September
Temperature
September brings an average high-temperature of a still tropical 86.9°F (30.5°C), showing a slight difference from August's 91.4°F (33°C). An average low-temperature of 66.6°F (19.2°C) is expected during September.Heat index
The heat index for September is appraised at a fiery hot 98.6°F (37°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Heat index evaluations are typically in the context of light winds and shaded environments. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
