Weather in September
Temperature
Arrival of September comes with a reduction in the average high-temperature, falling from a tropical 32.4°C (90.3°F) in August to a moderately hot 27.2°C (81°F). Nighttime temperature experiences an average drop to a moderate 15.6°C (60.1°F) in September.Heat index
September's heat index is computed to be 27°C (80.6°F). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
