Weather in September
Temperature
September experiences an average high-temperature of a still hot 32.6°C (90.7°F), barely different from August's 34.6°C (94.3°F). In the month of September, the average temperature dips to a moderately hot 26.3°C (79.3°F) during the night.Heat index
In September, the average heat index is appraised at a sweltering 39°C (102.2°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
Humidity
The average relative humidity in September is 62%.Rainfall
In September, the rain falls for 4.2 days. Throughout September, 4mm (0.16") of precipitation is accumulated. Throughout the year, there are 35.5 rainfall days, and 65mm (2.56") of precipitation is accumulated.Daylight

Sunshine
The average sunshine in September is 9.8h.UV index
In September, the average daily maximum UV index is 7. A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for the ordinary person.Note: A typical high UV index of 7 in September suggests the following recommendations:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
