Weather in September
Temperature
As September commences, the average high-temperature subtly reduces, transitioning from a hot 31.5°C (88.7°F) in August to a warm 27.2°C (81°F). During September, the nighttime temperature presents a clear descent from the daily peaks, falling to an average of 14.4°C (57.9°F).Heat index
September's heat index is computed to be 27°C (80.6°F). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather 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. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
