Weather in September

Throughout September, the heat index is evaluated at a hot 31°C (87.8°F). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
