Weather in September
Temperature
September, noted for its average high-temperature of 29.6°C (85.3°F) and an average low-temperature of 13.7°C (56.7°F), is considered the warmest month.Heat index
For most parts of September, the heat index is evaluated at a hot 30°C (86°F). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
