Weather in September
Temperature
August's transformation into September witnesses an average high-temperature of a still tropical 87.4°F (30.8°C), noting a minor change from the preceding month. During the month of September, an average temperature of 70.5°F (21.4°C) is noted during the nights.Heat index
For September, the heat index is calculated to be an extremely hot 104°F (40°C). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
