Weather in September
Temperature
August's transformation into September witnesses an average high-temperature of a still tropical 87.1°F (30.6°C), noting a minor change from the preceding month. Throughout September, the temperature falls to an average low of 67.8°F (19.9°C).Heat index
The heat index in September is appraised at a fiery hot 100.4°F (38°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. 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 'feels like' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
