Weather in September
Temperature
In September, the average high-temperature registers at a still tropical 86.9°F (30.5°C), nearly identical to August's 90.5°F (32.5°C). During September, the nighttime temperature averages to a pleasant 69.6°F (20.9°C).Heat index
The heat index for September is evaluated at a fiery hot 102.2°F (39°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
