Weather in September
Temperature
With the transition into September, Shemshi notes an average high-temperature of a still hot 33.5°C (92.3°F), closely resembling August. The nights of September in Shemshi cool down to an average low of 29.5°C (85.1°F), subtly lower than daytime highs.Heat index
The heat index value for September is evaluated at a scorching 41°C (105.8°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

With the absence of protection, damage to skin and eyes can occur instantly. Ensure precautions are taken. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
