Weather in September
Temperature
Dema's entry into September measures an average high-temperature of a torrid 35°C (95°F), closely parallel to the preceding month. Throughout September nights, Dema registers an average low-temperature of 24.9°C (76.8°F).Heat index
The heat index in September is evaluated at a life-threatening hot 45°C (113°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.It is important to note that the heat index values are for shaded areas and light wind scenarios. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', 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. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

In September, the average relative humidity is 59%.Rainfall
In September, the rain falls for 10.2 days. Throughout September, 37mm (1.46") of precipitation is accumulated. In Dema, during the entire year, the rain falls for 66.1 days and collects up to 257mm (10.12") of precipitation.Daylight

Sunshine
The average sunshine in September is 9.6h.UV index
The average daily maximum UV index in September is 8. A UV Index of 8 to 10 symbolizes a very high health vulnerability from unprotected exposure to Sun's UV rays for the ordinary person.Note: In September, a regular UV index of 8 translates into these guidelines:
Always remain cautious. Unprotected skin and eyes are prone to swift harm. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
