Weather in September
Temperature
The arrival of September corresponds with a light shift in temperature, down from a tropical 92.8°F (33.8°C) in August to a warm 84.6°F (29.2°C). During September, Witcher records an average temperature of 65.7°F (18.7°C) at night.Heat index
In September, the average heat index is estimated at a tropical 89.6°F (32°C). Enduring exposure and unrelenting activity might cause a state of weariness, potentially leading to heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
