Weather in September
Temperature
September, with its high-temperature average of 32.2°C (90°F) and a low-temperature average of 19°C (66.2°F), is the warmest month.Heat index
During September, the heat index is appraised at a torrid 35°C (95°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
Humidity
The months with the lowest humidity are August and September, with an average relative humidity of 52%.Rainfall
In September, the rain falls for 8.9 days. Throughout September, 51mm (2.01") of precipitation is accumulated. Throughout the year, there are 208.9 rainfall days, and 1257mm (49.49") of precipitation is accumulated.Daylight

Sunshine

The months with the highest UV index are January, March through December, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for the average person.Note: An average UV index of 6 in September transforms into this advice:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
