Weather in September
Temperature
Timissa's shift into September is marked by a subtle change to a torrid 36.4°C (97.5°F) from August's 34.5°C (94.1°F) in temperature. In the month of September, the average temperature dips to a warm 26.5°C (79.7°F) during the night.Heat index
The heat index value for September is calculated to be a blistering 44°C (111.2°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.Data suggests that the heat index is set for environments in shade and with a light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. 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.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Sunshine

In September, the average daily maximum UV index is 8. A UV Index estimate of 8 to 10 represents a very high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.Note: During September, 8 as the daily maximum UV index converts into the following advice:
Immediate precautions are necessary; otherwise, skin and eyes might get damaged quickly. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly. Notice! The UV radiation of the Sun can be intensified nearly twofold due to the reflective quality of snow.
