Weather in September
Temperature
The shift into September uncovers an average high-temperature of a still hot 30°C (86°F), subtly different from the previous month. September nights register a minor temperature decline, steadying at a moderately hot 26.3°C (79.3°F).Heat index
For most parts of September, the heat index is calculated to be a fiery hot 37°C (98.6°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
