September weather forecast
Ombima, Congo

The first month of the spring, September, is still a tropical month in Ombima, Congo, with an average temperature varying between 22.7°C (72.9°F) and 31.4°C (88.5°F).

Temperature

With the onset of September, the average high-temperature stands at a still tropical 31.4°C (88.5°F), closely aligned with August's 32.9°C (91.2°F). Throughout the month of September, Ombima reports a steady low-temperature average of 22.7°C (72.9°F).

Heat index

The average heat index in September is estimated at an extremely hot 40°C (104°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Humidity

In September, the average relative humidity is 73%.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
