Weather in September
Temperature
The arrival of September sees an average high-temperature of a still tropical 87.4°F (30.8°C), hardly diverging from August's 90.7°F (32.6°C). During the month of September, the nighttime temperature falls to an average of 70.5°F (21.4°C).Heat index
In September, the average heat index is computed to be an extremely hot 104°F (40°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
