September weather forecastCanda, Angola

Weather in September

The first month of the spring, September, is also a hot month in Canda, Angola, with an average temperature ranging between min 18°C (64.4°F) and max 30.2°C (86.4°F).

Temperature

The transition into September notes an average high-temperature of a still tropical 30.2°C (86.4°F), revealing a mild distinction from the 31.3°C (88.3°F) in August. A noteworthy thermal contrast characterizes Canda's September nights, with temperatures averaging at a refreshing 18°C (64.4°F).

Heat index

The heat index value during September is appraised at a very hot 36°C (96.8°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

The average relative humidity in September in Canda is 70%.

Rainfall

In Canda, in September, during 24.6 rainfall days, 82mm (3.23") of precipitation is typically accumulated. In Canda, during the entire year, the rain falls for 261.7 days and collects up to 1536mm (60.47") of precipitation.

UV index

April through September, with an average maximum UV index of 6, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the average person.
Note: A maximum high UV index of 6 in September translates into the following recommendations:
Deter overexposure. Protecting against the sun's effects is essential. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
