Weather in September
Temperature
The start of September involves a temperature drop, moving from a tropical 94.1°F (34.5°C) in August to a moderately hot 85.1°F (29.5°C). Sentinel experiences a mean low-temperature of 66°F (18.9°C) during September.Heat index
September's heat index is evaluated at a hot 89.6°F (32°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance 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.
