Weather in September
Temperature
September notes an average high-temperature of a still warm 27.9°C (82.2°F), subtly differing from August's 27.3°C (81.1°F). Nighttime temperature dips to a mean of 21.9°C (71.4°F) during September.Heat index
Throughout September, the heat index is evaluated at a tropical 31°C (87.8°F). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
