Weather in September
Temperature
September brings an average high-temperature of a still tropical 31.6°C (88.9°F), showing a slight difference from August's 32.3°C (90.1°F). September nights reflect a consistent temperature dip to a warm 27.3°C (81.1°F), a slight descent from daytime peaks.Heat index
September's heat index is evaluated at an extremely hot 40°C (104°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
