Weather in September
Temperature
The arrival of September records an average high-temperature of a still hot 30.3°C (86.5°F), closely related to the 30.7°C (87.3°F) observed in August. September nights are marked by an average low-temperature of 23.9°C (75°F).Heat index
The heat index value for September is evaluated at a scorching 41°C (105.8°F). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.
Humidity
The months with the highest humidity are July, September and October, with an average relative humidity of 86%.Rainfall
In September, the rain falls for 22.5 days. Throughout September, 134mm (5.28") of precipitation is accumulated. Throughout the year, there are 260 rainfall days, and 1127mm (44.37") of precipitation is accumulated.Daylight

Sunshine
In September, the average sunshine is 7.5h.UV index
The months with the highest UV index are February through October, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for the ordinary person.Note: The daily high UV index of 7 during September translates into the following recommendations:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
