September weather forecast
Kwilu Ngongo, Democratic Republic of Congo

Kwilu Ngongo sets foot into September with longest daylight hours at 12.1 hours, another defining characteristic of the changing seasons. Marking a clear transition into a month of moderate climate, rainfall starts to pick up again. Wind movements continue to influence the local weather and hold steady their narration in the atmospheric theatre. This month practically feels like a weather potpourri with hints of previous patterns while introducing a prelude to the approaching peak rainfall season. As the curtain falls on September, a rainy stage is set for the coming months.

Temperature

September's onset records a minor alteration in the average high-temperature to a still hot 32°C (89.6°F) from August's 32.4°C (90.3°F). September's average low-temperature reading settles at a pleasant 21.2°C (70.2°F).

Heat index

The average heat index in September is calculated to be a sweltering 38°C (100.4°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

The average relative humidity in September is 63%.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses.
