Weather in September
Temperature
The transition from August to September sees an average high-temperature of a still tropical 87.3°F (30.7°C), indicating a minor variance from the prior month. Nighttime temperatures hover around an average low of 70.3°F (21.3°C) in September.Heat index
The heat index in September is evaluated at a blisteringly hot 104°F (40°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. 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.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
