During September, Nadawah observes a subtle ascent to a still hot 88.3°F (31.3°C) from August's 92.7°F (33.7°C) in the average high-temperature. September in Nadawah sees the temperature falling to a mean low of 67.5°F (19.7°C).

Heat index

The heat index in September is appraised at a sweltering 102.2°F (39°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
