Weather in September
Temperature
Al Ghiran's transition from August to September introduces an average high-temperature of a moderately hot 29.5°C (85.1°F), marking an insignificant variation from the 30.7°C (87.3°F). September nights register a minor temperature decline, steadying at a still warm 25.5°C (77.9°F).Heat index
During September, the heat index is evaluated at a tropical 32°C (89.6°F). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
