Weather in September
Temperature
September is the warmest month, with an average high-temperature of 32.3°C (90.1°F) and an average low-temperature of 22.3°C (72.1°F).Heat index
For most parts of September, the heat index is appraised at a torrid 39°C (102.2°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

In September, the average relative humidity is 64%.Rainfall
In September, the rain falls for 12 days. Throughout September, 18mm (0.71") of precipitation is accumulated. Throughout the year, there are 228.5 rainfall days, and 1086mm (42.76") of precipitation is accumulated.Daylight

Sunshine
The average sunshine in September is 8h.UV index
March, April, August and September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV rays for the ordinary person.Note: A maximum high UV index of 7 in September translates into the following recommendations:
Resist extreme sun exposure. Guarding against solar damage is essential. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
