Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from 93.7°F (34.3°C) in August to a still tropical 88°F (31.1°C). New Territory observes an average low-temperature of 72.1°F (22.3°C) during September.Heat index
In September, the heat index is evaluated at a blistering 104°F (40°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
