Weather in September
Temperature
The dawn of September registers an average high temperature of a still hot 32.3°C (90.1°F), nearly the same as the 32.3°C (90.1°F) observed in August. Birdaf sustains a near constant temperature throughout September, with nighttime averages of 27.7°C (81.9°F).Heat index
In September, the heat index is estimated at a blisteringly hot 40°C (104°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.When referencing the heat index, its values are suitable for shady environments and light breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
