Weather in September
Temperature
September's advent denotes a minor fluctuation in the average high-temperature to a still warm 28.7°C (83.7°F) from August's 28.9°C (84°F). A mean low-temperature of 27.5°C (81.5°F) is a distinguishing feature of September, indicating a slight dip from daytime highs.Heat index
The heat index value during September is estimated at a hot 33°C (91.4°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. 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 especially crucial for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
