Weather in September
Temperature
Cacula's temperatures tend to reach their peak averages in September, with a high of 29.6°C (85.3°F) and a low of 13.7°C (56.7°F).Heat index
The heat index value for September is appraised at a tropical 30°C (86°F). Enduring exposure and continuous activity might cause a feeling of tiredness and induce heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
