Throughout September, Niare records a steady low-temperature average of 22.9°C (73.2°F), a minor decrease from its daytime counterpart.Heat index
September's mean heat index is computed to be a tropical 30°C (86°F). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Heat index details are generally centered around shaded locations and a mild breeze. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
