Weather in September
Temperature
The arrival of September correlates with a minor temperature reduction, down from August's hot 88.3°F (31.3°C) to a moderately hot 81.9°F (27.7°C). Lulu encounters an average low-temperature of 60.8°F (16°C) during September nights.Heat index
For September, the heat index is evaluated at a tropical 86°F (30°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. 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 'apparent temperature' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely vital to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
