Weather in September
Temperature
The onset of September marks an average high-temperature of a very hot 35.5°C (95.9°F), hardly differing from August's 33.8°C (92.8°F). In September, Alamini's temperature tends to fall to an average low of 25.6°C (78.1°F) during the night.Heat index
The heat index in September is calculated to be a blisteringly hot 43°C (109.4°F). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. 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. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Protection is paramount; otherwise, swift harm can come to the skin and eyes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
