Weather in September
Temperature
On the advent of September, Cunaia's average high-temperature exhibits a minor adjustment to a still tropical 31.6°C (88.9°F) from August's 30.8°C (87.4°F). Cunaia reports a consistent average low-temperature of 23.2°C (73.8°F) throughout September nights.Heat index
September's average heat index is evaluated at a burning hot 45°C (113°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.Heat index data is primarily for areas with shade and subjected to light winds. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
