Weather in September
Temperature
The warmest period is September, when temperatures fluctuate between an average high of 29.6°C (85.3°F) and a low of 13.7°C (56.7°F).Heat index
September's average heat index is estimated at a tropical 30°C (86°F). Enduring exposure and ongoing activity could cause a sense of fatigue and subsequent heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
