Weather in September
Temperature
The introduction of September notes a subtle temperature variation to a still moderately hot 27.1°C (80.8°F) from August's 26.6°C (79.9°F). During September's nights, Amahusu notes a minor temperature decline, reaching an average of 25.2°C (77.4°F).Heat index
September's average heat index is estimated at a tropical 30°C (86°F). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.Heat index determinations are made taking into account the shade and light air movements. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
