Weather in September
Temperature
The transition into September marks the average high-temperature at a still fiery hot 36.5°C (97.7°F), differing minimally from August's 36°C (96.8°F). The nights of September anticipate an average low-temperature of 26.4°C (79.5°F).Heat index
September's mean heat index is calculated to be a life-threatening hot 50°C (122°F). Keep guard: Heat cramps and heat exhaustion are likely. Continued activity increases the risk of heatstroke.Consider that heat index readings are for situations in the shade and light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

The months with the highest UV index are March through July, September and October, with an average maximum UV index of 8. A UV Index value of 8 to 10 symbolizes a very high health hazard from unsafe exposure to UV radiation for the ordinary person.Note: In September, the average maximum UV index of 8 translates into the following recommendations:
Always safeguard yourself; without protection, skin and eyes can get damaged instantly. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
