Weather in September
Temperature
Ar Raha marks the start of September with an average high-temperature of a still tropical 30.9°C (87.6°F), hinting at a slight fluctuation from August's 33.8°C (92.8°F). The significant decline in Ar Raha's temperature, from day to night, averages of 18.4°C (65.1°F) in September.Heat index
The heat index for September is evaluated at a tropical 32°C (89.6°F). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', unifies temperature and humidity readings to offer a comprehensive feel of warmth. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
