Weather in September
Temperature
As Angola welcomes September, the average high-temperature records at a still hot 87.8°F (31°C), marking an insignificant deviation from the prior month. Angola, during the nights of September, experiences an average temperature drop to a pleasant 68.9°F (20.5°C).Heat index
For September, the heat index is estimated at an extremely hot 105.8°F (41°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Take precautions against overexposure. Protection against sun damage is needed. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
