Weather in September
Temperature
The onset of September marks an average high-temperature of a still warm 28°C (82.4°F), hardly differing from August's 27.8°C (82°F). Nighttime temperatures in September average to an enjoyable 16.6°C (61.9°F).Heat index
The heat index value during September is computed to be a tropical 32°C (89.6°F). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are primarily vital for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
