Weather in September
Temperature
The arrival of September denotes a barely perceptible change in the average high-temperatures to a still tropical 33.7°C (92.7°F) from August's 34.6°C (94.3°F). In Dehban, a slight decrease from the daytime peak is noted during the month of September, with an average low-temperature of 32.3°C (90.1°F).Heat index
The heat index for September is estimated at a scorching 44°C (111.2°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
