Weather in September
Temperature
September reports an average high-temperature of a still tropical 88.2°F (31.2°C), slightly varied from August's 90.7°F (32.6°C). September nights experience a consistent temperature drop to a pleasant 73.2°F (22.9°C).Heat index
The heat index in September is computed to be an extremely hot 105.8°F (41°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. 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. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
