Weather in September
Temperature
September's arrival coincides with a subtle temperature rise, moving from August's hot 30.5°C (86.9°F) to a still tropical 33.5°C (92.3°F). In Koukou Angarana, September nights witness a steady temperature drop to a warm 23.3°C (73.9°F).Heat index
Throughout September, the heat index is computed to be a blistering 43°C (109.4°F). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
