Weather in September
Temperature
The onset of September results in a small decrease in the average high-temperature, moderately receding from a tropical 33.3°C (91.9°F) in August to a moderately hot 28.3°C (82.9°F). An average temperature of 18.1°C (64.6°F) is recorded during the nights in September.Heat index
September's mean heat index is computed to be a tropical 30°C (86°F). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
