Weather in September

In September, the average heat index is evaluated at a tropical 89.6°F (32°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
