Weather in September
Temperature
September's advent notes a subtle adjustment in average high-temperature to a still moderately hot 27.1°C (80.8°F) from August. Ema's nighttime temperatures in September settle close to daytime highs at an average of 25.2°C (77.4°F).Heat index
September's average heat index is estimated at a hot 30°C (86°F). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.One should consider that heat index numbers are for shaded settings and light wind. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. 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.
