Weather in September
Temperature

During September, the heat index is appraised at a tropical 34°C (93.2°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
